The out parameter 'parameter' must be assigned to before control leaves the current method

A parameter marked with the out keyword was not assigned a value in the method body. For more information, see Passing Parameters

The following sample generates CS0177:

C#

// CS0177.cs  
public class MyClass  
{  
   public static void Foo(out int i)   // CS0177  
   {  
   // uncomment the following line to resolve this error  
   //   i = 0;  
   }  
  
   public static void Main()  
   {  
       int x = -1;  
       Foo(out x);  
   }  
}
