GenericDelegates

This example demonstrates how generic delegates are translated to C++. They are declared using special type System::MulticastDelegate from asposecpplib.

Additional command-line options passed to CodePorting.Translator.Cs2Cpp: none.

Source C# Code 

using System;

namespace TypesPorting
{
    public delegate TOut GenericDelegate<TIn, TOut>(TIn value);

    public delegate TOut GenericDelegateWithTypeConstraint<TIn, TOut>(TIn value) where TIn : ICloneable where TOut : IConvertible;

    public delegate TOut GenericDelegateWithClassConstraint<TIn, TOut>(TIn value) where TIn : class where TOut : class;

    public delegate TOut GenericDelegateWithStructConstraint<TIn, TOut>(TIn value) where TIn : struct where TOut : struct;

    public delegate TOut GenericDelegateWithNewConstraint<TIn, TOut>(TIn value) where TIn : new() where TOut : new();

    public delegate TOut GenericDelegateWithSeveralConstraints<TIn, TOut>(TIn value) where TIn : class, ICloneable, new() where TOut : struct, IConvertible;
}
