Compiler Error CS1715

'Type1': type must be 'Type2' to match overridden member 'MemberName'

This error is the same as Compiler Error CS0508, except that CS0508 now only applies to methods that have return types, while CS1715 applies to properties and indexers that only have 'types' instead of 'return types'.

Example

The following code generates CS1715.

C#
// CS1715.cs  
abstract public class Base  
{  
    abstract public int myProperty  
    {  
        get;  
        set;  
    }  
}  
  
public class Derived : Base  
{  
    int myField;  
    public override double myProperty  // CS1715  
    // try the following line instead  
    // public override int myProperty  
    {  
        get { return myField; }  
        set { myField;= value; }  
    }  
  
    public static void Main()  
    {  
        Derived d = new Derived();  
        d.myProperty = 5;  
    }  
}
