Compiler Error CS1546

Property, indexer, or event 'property' is not supported by the language; try directly calling accessor method 'accessor'

Your code is consuming an object that has a default indexed property and tried to use the indexed syntax. To resolve this error, call the property's accessor method. For more information on indexers and properties, see Indexers (C# Programming Guide).

The following sample generates CS1546.

This code sample consists of a .cpp file, which compiles to a .dll, and a .cs file, which uses that .dll. The following code is for the .dll file, and defines a property to be accessed by the code in the .cs file.

// CPP1546.cpp
// compile with: /clr /LD
using namespace System;
public ref class MCPP
    property int Prop [int,int]
        int get( int i, int b )
            return i;

This is the C# file.

// CS1546.cs
// compile with: /r:CPP1546.dll 
using System;
public class Test
    public static void Main()
        int i = 0;
        MCPP mcpp = new MCPP();
        i = mcpp.Prop(1,1); // CS1546
        // Try the following line instead:
        // i = mcpp.get_Prop(1,1);
