Compiler Error CS0102

  • Άρθρο

The type 'type name' already contains a definition for 'identifier'

A class contains multiple declarations for identifiers with the same name at the same scope. To fix the error, rename the duplicate identifiers.

Example

The following sample generates CS0102.

// CS0102.cs  
// compile with: /target:library  
namespace MyApp  
{  
   public class MyClass  
   {  
      string s = "Hello";  
      string s = "Goodbye";   // CS0102  
  
      public void GetString()  
      {  
         string s = "Hello again";   // method scope, no error  
      }  
   }  
}
