本文介绍了从符获取自定义类的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

调用 Web服务之后,它会返回一个对象(此对象是一个自定义对象类)客户端。所以,我想从这个对象自定义类转换。

After calling Webservices, it returns an object (This object is a custom object class) to client. So, I want to convert from this object to custom class.

-Webservices:

-Webservices:

[WebMethod]
public Cls_ROLES GetRoles(int firstNum)
{
    Cls_ROLES o = new Cls_ROLES();
    o.Role_ID = 2;
    o.RoleName = "binh";
    return o;
}

- 客户端:

-Client:

+功能:

public object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args)
{
    System.Net.WebClient client = new System.Net.WebClient();
    //-Connect To the web service
    using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl"))
    {
        //--Now read the WSDL file describing a service.
        ServiceDescription description = ServiceDescription.Read(stream);
        ///// LOAD THE DOM /////////
        //--Initialize a service description importer.
        ServiceDescriptionImporter importer = new ServiceDescriptionImporter();
        importer.ProtocolName = "Soap12"; // Use SOAP 1.2.
        importer.AddServiceDescription(description, null, null);
        //--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client;
        //--Generate properties to represent primitive values.
        importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties;
        //--Initialize a Code-DOM tree into which we will import the service.
        CodeNamespace nmspace = new CodeNamespace();
        CodeCompileUnit unit1 = new CodeCompileUnit();
        unit1.Namespaces.Add(nmspace);
        //--Import the service into the Code-DOM tree. This creates proxy code
        //--that uses the service.
        ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1);
        if (warning == 0) //--If zero then we are good to go
        {
            //--Generate the proxy code 
            CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp");
            //--Compile the assembly proxy with the appropriate references
            string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" };
            CompilerParameters parms = new CompilerParameters(assemblyReferences);
            CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1);
            //-Check For Errors
            if (results.Errors.Count > 0)
            {
                StringBuilder sb = new StringBuilder();
                foreach (CompilerError oops in results.Errors)
                {
                    sb.AppendLine("========Compiler error============");
                    sb.AppendLine(oops.ErrorText);
                }
                throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString());
            }
            //--Finally, Invoke the web service method 
            Type foundType = null;
            Type[] types = results.CompiledAssembly.GetTypes();
            foreach (Type type in types)
            {
                if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol))
                {
                    Console.WriteLine(type.ToString());
                    foundType = type;
                }
            }

            object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString());
            MethodInfo mi = wsvcClass.GetType().GetMethod(methodName);
            object o = new object();
            o=mi.Invoke(wsvcClass, args);
            return o;
        }
        else
        {
            return null;
        }
    }
}

+的Page_Load功能:

+Page_Load function:

Line 1:object[] args=new object[1];
Line 2:args[0]=1;  
Line 3:o = this.CallWebService("http://localhost:1814/HelloServices/Service.asmx", "Hello", "GetRoles", args);

返回在3号线的对象(此对象是一个自定义对象类)客户端。所以,我想从这个对象自定义类(Cls_Role对象)进行转换。
// ================================================ ======================================
// ================================================ ======================================
// ================================================ ======================================
作为Selalu_Ingin_Belajar的回答,我可以从符价值客户的罚款。

it returns an object at Line3 (This object is a custom object class) to client. So, I want to convert from this object to custom class(Cls_Role object). //====================================================================================== //====================================================================================== //====================================================================================== As Selalu_Ingin_Belajar's answer,I can get value from webservices to client fine.

对象yourObject =新的对象();

object yourObject = new object();

foreach (PropertyInfo property in yourObject.GetType().GetProperties())
{           
    object value = property.GetValue(yourObject , null);
    Console.WriteLine("{0} = {1}", property.Name, value);
}

在它旁边,当我申请到另一个项目,这表明另一个错误:参数数量不匹配。
如果我使用AddWebReference通过的VisualStudio工具。
它会自动生成Reference.cs file.It包含以下内容:

Beside it,When I apply to another project,It show another error: Parameter count mismatch. If I use AddWebReference by VisualStudio tool. It'll auto generate Reference.cs file.It contain:

/// <remarks/>
    [System.Web.Services.Protocols.SoapRpcMethodAttribute("", RequestNamespace="urn:ALBAPI", ResponseNamespace="urn:ALBAPI")]
    [return: System.Xml.Serialization.SoapElementAttribute("info")]
    public ResponseInfo getSetupLicenseRows(out SetupLicenseRowsValues values) {
        object[] results = this.Invoke("getSetupLicenseRows", new object[0]);
        values = ((SetupLicenseRowsValues)(results[1]));
        return ((ResponseInfo)(results[0]));
    }

原来如此,这很容易通过传递对象SetupLicenseRowsValues​​类从Web客户端调用。
现在,我必须manually.Don't传递参数,以Web服务使用这个生成的文件。

So that,It's easy to call from webClient by passing a object SetupLicenseRowsValues class. Now,I must pass parameter to WebServices by manually.Don't use this generate file.

客户:

        string WebserviceUrl = "http://192.168.2.19:3333/ALBAPI.wsdl";
        string serviceName = "ALBAPI";
        string methodName = "getSetupLicenseRows";
        object[] args=new object[0];
        object sSessionID = CallWebService(WebserviceUrl, serviceName, methodName,args);
        foreach (PropertyInfo property in sSessionID.GetType().GetProperties())

            object value = property.GetValue(sSessionID, null);

            Console.WriteLine("{0} = {1}", property.Name, value);
        }

    }

现在,它显示错误参数计数不匹​​配的线路错误。
感谢您的帮助反正

Now,It show error "Parameter count mismatch" at Line error. Thanks for your help anyway

推荐答案

现在,如果我理解正确的,因为你通过动态建立代理(而不是使用服务引用)繁琐的工作去了,这将意味着你的消费code,不包含任何可能的服务可能会返回对象的实际定义。

Now, if i understood correctly, and since you went through the cumbersome effort of dynamically building the proxy (instead of using service references), that would mean that your consumer code, does not contain an actual definition for any of the objects your possible service may return.

在这种情况下,我没有看到很多,其中通过静态类型code就可以实现这一目标。
你可以尝试使用动态,希望你的反应具有结构化您所期望的,但不知道真正的类型。
如:

In that case I don't see many ways in which through statically typed code you can accomplish that. You could try using dynamic and hope that your response has the "structure" you expect, but without knowing the real type. Such as:

dynamic returnValue = CallWebservice(someEndpoint, someServiceName, ...);
//now you can access all the properties of returnValue, for example:
Console.WriteLine(returnValue.Role_ID);
//but you won't have intellisense, may be error prone, and will prevent you from proper refactoring
