如何将字节数组传输到WCF服务 [英] How to transfer the byte array to WCF service

问题描述

我正在尝试将excel文件转换为字节数组并将其传递给WCF服务方法。

我收到以下异常。请帮我解决这个问题。



这是下面的代码块，我收到错误和

SaveData（*** ）方法是调用WCF服务的方法

Hi,

I'm trying to convert an excel file to byte array and passing the same to WCF service method.
I'm getting the following exception. Please help me to resolve this issue.

This is the below code chunk where I'm getting error and
SaveData(***) method is the one which calls the WCF service

string strFile = ViewState[GlobalConstants.strVsfilePath].ToString();
                    DataTable dtSaveData = new DataTable();
                    dtSaveData = (DataTable)ViewState[GlobalConstants.strVsOrginal];
                    DataSet dsSaveData = new DataSet();
                    dsSaveData.DataSetName = "dsfff";
                    dsSaveData.Tables.Add(dtSaveData);
                    dsSaveData.Tables[0].TableName = "dtfff";
                    string strResult = string.Empty;
                    MemoryStream stream = new MemoryStream();
                    dtSaveData.WriteXml(stream, true);
                    stream.Seek(0, SeekOrigin.Begin);
                    StreamReader sr = new StreamReader(stream);
                    string strInputXML = sr.ReadToEnd();
                    string strModifiedXml = strInputXML.Replace("+05:30", "");
                    byte[] btData = FileToByteArray(strFile);
                    File.Delete(strFile);
                    //cByteTransfer objByteTransfer = new cByteTransfer();
                    //objByteTransfer.BTransfer = btData;
                    Stream streamData = new MemoryStream(btData);

                    adminsvc.SaveData(strModifiedXml, dsSaveData.DataSetName, dsSaveData.Tables[0].TableName, strType, strLoginName, "FIXED", btData, (string)ViewState["strWorkbookName"], (string)ViewState["SheetName"]);

推荐答案

我在basichttpbinding - >绑定标签中设置了maxStringContentLength =65536000并且它有效。



并且还添加了basichttpbinding下使用的绑定名称 - >这里绑定到端点标签作为属性binding =basicBinding



请查看使用的配置如下所示

I have set the maxStringContentLength="65536000" in basichttpbinding-->binding tag and it worked.

And also added the name of the binding used under basichttpbinding-->binding here into the endpoint tag as an attribute binding="basicBinding"

Please find the configuration used as below

<system.serviceModel>
    <bindings>

      <basicHttpBinding>
       
        <binding name="basicBinding" closeTimeout="00:10:00" openTimeout="00:10:00" sendTimeout="00:10:00" maxBufferSize="2147483647"  maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="65536000"

          maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
        </binding>
        </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceTypeBehaviors">
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="MY_SERVICE.cMY_Module"

             behaviorConfiguration="MyServiceTypeBehaviors">
        <endpoint address="http://localhost:1111/MY_Service.svc" binding="basicBinding"

             contract="MY_SERVICE.IMyService" bindingConfiguration="basicHttpBinding"/>
        <endpoint contract="IMetadataExchange"

           binding="mexHttpBinding" address="mex"/>
      </service>
    </services>
  </system.serviceModel>
