推荐答案

将此代码放入web.config

并查看您的工具包版本

< br $> b $ b

put this code in web.config
and check out your version of an toolkit

<configsections>
		
			<sectiongroup name="system.web.extensions">
        type="System.Web.Configuration.SystemWebExtensionsSectionGroup, 
      System.Web.Extensions, Version=3.5.0.0, Culture=neutral,  
      PublicKeyToken=31BF3856AD364E35">

      <sectiongroup name="scripting">
        type="System.Web.Configuration.ScriptingSectionGroup, 
        System.Web.Extensions, Version=3.5.0.0, Culture=neutral, 
        PublicKeyToken=31BF3856AD364E35">

        

        <sectiongroup name="webServices">
          type="System.Web.Configuration.ScriptingWebServicesSectionGroup,
          System.Web.Extensions, Version=3.5.0.0, Culture=neutral, 
          PublicKeyToken=31BF3856AD364E35">

          

          
         

          

        </sectiongroup>
      </sectiongroup>
    </sectiongroup>

</configsections>

谢谢

thank you

在Web.Config文件中添加以下行，它将起作用.....它的工作原理在我的情况下因为我有同样的问题。

Add the following line in Web.Config file and it will work.....it works in my case coz i had same problem.

<system.web>

您可以通过将项目引用的Copy Local属性设置为true来解决此问题！



说明



1-在解决方案资源管理器中，单击显示所有文件按钮以显示参考节点。

2-打开项目的参考节点。

3-右键单击参考列表中的参考，然后单击属性。 />
与该参考相关联的属性显示在属性窗口的列表中。

4-从中选择复制本地左侧列，然后单击右侧列中的箭头将值更改为 True 或 False 。



您也可以使用以下代码用于识别缺少的内容

You may solve this issue by setting the Copy Local attribute of your project's references to true!

Instructions

1- In Solution Explorer, click the Show All Files button to display the References node.
2- Open the References node for the project.
3- Right-click a reference in the References list, and click Properties.
The properties associated with that reference appear in a list in the Properties window.
4- Select Copy Local from the left-hand column, and then click the arrow in the right-hand column to change the value to True or False.

You may also use the following code to identify what is missing

<pre lang="c#">

使用System.IO;

使用System.Reflection;

使用System.Text;



尝试

{

//导致错误的代码在这里。

}

catch（ReflectionTypeLoadException ex）

{

StringBuilder sb = new StringBuilder（）;

foreach（ex.LoaderExceptions中的异常exSub）

{

sb。 AppendLine（exSub.Message）;

FileNotFoundException exFileNotFound = exSub as FileNotFoundException;

if（exFileNotFound！= null）

{

if（！string.IsNullOrEmpt y（exFileNotFound.FusionLog））

{

sb.AppendLine（Fusion Log：）;

sb.AppendLine（exFileNotFound.FusionLog ）;

}

}

sb.AppendLine（）;

}

string errorMessage = sb.ToString（）;

//根据您的应用程序显示或记录错误。

}
