问题描述
我的LINQ表达式不起作用。最有可能是.NET版本。
当我运行程序时，网页显示此错误而不是错误：
My LINQ expression does not works. Most probably it was for the version of .NET.
Instead of error when I run the program the web page shows this error :
Source Error:
Line 161: List<string> globalTablesList = GetTableNames(dt);
Line 162:
Line 163: List<string> commonTableList = (from item in distinctItem
Line 164: where globalTablesList.Contains(item)
Line 165: select item).ToList();
Source File: d:\BIPORTAL-Dev\App_Code\Service.cs Line: 163

从这里我们可以看到没有任何部分选择低于3.5版本。但是错误显示它在版本2.0上运行我将如何解决问题？
From here we can see there is no portion select less than version 3.5. But error show it runs on version 2.0 how i will solve the problem?
