Compiler Error C3103

'argument': repeated named argument

An attribute can not repeat named arguments.

For more information, see User-Defined Attributes (C++ Component Extensions).

The following sample generates C3103.

// C3103.cpp
// compile with: /clr /c
using namespace System;

[AttributeUsage(AttributeTargets::All)]
public ref class Attr : public Attribute {
public:
   int m_t;
};

[Attr(m_t = 10, m_t = 1)]   // C3103
// try the following line instead
// [Attr(m_t = 10)]
ref class A {};
