无法使用Windows服务或任务计划程序读取xsd路径 [英] UNable to read xsd path using windows service or task scheduler

问题描述

我已在下面提供了我的代码

  public   static   void  XMLSchema（）
 {
  string  pathToXmlFile = < span class =code-string> @  .. \..\XML \Sample.xml; 
  string  pathOfXmlSchemaFile =  @  .. \\ \\..\Sample.xsd; 
  try  
 {
 XmlReaderSettings xmlSettings =  new  XmlReaderSettings（）; 
 xmlSettings.Schemas =  new  System.Xml.Schema.XmlSchemaSet（）; 
 使用（ var  stream = System.Reflection.Assembly.GetExecutingAssembly（）。GetManifestResourceStream（pathOfXmlSchemaFile ））
 {
  //   Log.WriteLog（ValidateXmlFileElement，ValidateXmlFileElement started） ;  
 XmlReader xmlReader = XmlReader.Create（pathOfXmlSchemaFile）; 
 xmlSettings.Schemas.Add（ ，xmlReader）; 
 
} 
 xmlSettings.ValidationType = ValidationType.Schema; 
 
 XmlReader reader = XmlReader.Create（pathToXmlFile，xmlSettings）; 
  while （reader.Read（））; 
 Console.WriteLine（  success）; 
} 
  catch （例外情况）
 {
  //   Log.WriteLog（ValidateXmlFileElement，ValidateXmlFileElement completed）;  
  string  errorMessage =  string  .Format（  {0} {1 }，  \t，ex.Message.ToString（），ex .InnerException）; 
 Console.WriteLine（errorMessage）; 
  //   Log.WriteLog（ValidateXmlFileElement，errorMessage）;  
} 
 

如果我使用Windows调度程序或任务调度程序运行此代码，所以我是在下面给出的这一行中得到错误

  var  stream = System.Reflection.Assembly.GetExecutingAssembly（ ）.GetManifestResourceStream（pathOfXmlSchemaFile 

这里的流值为null，



即使我设置了像build这样的xsd文件属性动作=在vs2010中嵌入资源



任何人都可以帮我解决这个问题，请提前谢谢





谢谢

解决方案

GetManifestR esourceStream function [ ^ ]用于读取程序集中嵌入的资源。您正在将相对路径传递给磁盘上的文件。无论项目类型如何，这都将无法工作。



如果您想要读取嵌入式资源，则需要将有效的资源名称传递给 GetManifestResourceStream 功能：

 使用（ var  stream = System.Reflection.Assembly.GetExecutingAssembly（）。GetManifestResourceStream（ 命名空间。 Of.Your.Resource.Sample.xsd））
 {
 ... 
} 

如果你想从磁盘读取文件，那么使用正确的方法：

 使用（ var  stream = System.IO.File.OpenRead（ @  .. \..\Sample.xsd））
 {
 ... 
} 

I have given my code below

public static void XMLSchema()
       {
           string pathToXmlFile = @"..\..\XML\Sample.xml";
           string pathOfXmlSchemaFile = @"..\..\Sample.xsd";
           try
           {
               XmlReaderSettings xmlSettings = new XmlReaderSettings();
               xmlSettings.Schemas = new System.Xml.Schema.XmlSchemaSet();
               using (var stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(pathOfXmlSchemaFile))
               {
                   //Log.WriteLog("ValidateXmlFileElement", "ValidateXmlFileElement started");
               XmlReader xmlReader = XmlReader.Create(pathOfXmlSchemaFile);
                   xmlSettings.Schemas.Add("", xmlReader);

               }
               xmlSettings.ValidationType = ValidationType.Schema;

               XmlReader reader = XmlReader.Create(pathToXmlFile, xmlSettings);
               while (reader.Read()) ;
               Console.WriteLine("success");
           }
           catch (Exception ex)
           {
               //Log.WriteLog("ValidateXmlFileElement", "ValidateXmlFileElement completed");
               string errorMessage = string.Format("{0}{1}", "\t", ex.Message.ToString(), ex.InnerException);
               Console.WriteLine(errorMessage);
               //Log.WriteLog("ValidateXmlFileElement", errorMessage);
           }

if i run this code using windows scheduler or task scheduler, so i am getting error in this line which is given below

var stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(pathOfXmlSchemaFile

here stream value is null,

even i set xsd file properties like build action=embeded resource in vs2010

Can anyone help me how to getrid of from this issue, thanks in advance


Thanks

解决方案

The GetManifestResourceStream function[^] is used to read a resource embedded in your assembly. You are passing a relative path to a file on disk. That will never work, regardless of the project type.

If you want to read an embedded resource, you need to pass a valid resource name to the GetManifestResourceStream function:

using (var stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("Namespace.Of.Your.Resource.Sample.xsd"))
{
    ...
}

If you want to read the file from disk, then use the correct method:

using (var stream = System.IO.File.OpenRead(@"..\..\Sample.xsd"))
{
    ...
}
