CS1044 – Cannot use more than one type in a for, using, fixed, or declaration statement

Reason for the Error & Solution

Cannot use more than one type in a for, using, fixed, or declaration statement

The compiler found an invalid statement.

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  
      {  
      }  
   }  
}
