编译器错误 CS1044Compiler Error CS1044

在 for、using、fixed 或声明语句中不能使用多个类型Cannot use more than one type in a for, using, fixed, or declaration statement

编译器发现了一个无效的语句。The compiler found an invalid statement.

以下示例生成 CS1044:The following sample generates CS1044:

// CS1044.cs  
using System;  
  
public class MyClass : IDisposable  
{  
   public void Dispose()  
   {  
      Console.WriteLine("Res1.Dispose()");  
   }  
  
   public static void Main()  
   {  
      using (MyClass mc1 = new MyClass(),  
             MyClass mc2 = new MyClass())   // CS1044, remove an instantiation  
      {  
      }  
   }  
}
