C# generic constraints code example

Example 1: c# multiple template constraints

public TResponse Call<TResponse, TRequest>(TRequest request)
    where TRequest : MyClass
    where TResponse : MyOtherClass

Example 2: csharp attributes as generics constraints

public static void Insert<T>(this IList<T> list, IList<T> items)
{
    var attributes = typeof(T).GetCustomAttributes(typeof(InsertableAttribute), true);

    if (attributes.Length == 0)
        throw new ArgumentException("T does not have attribute InsertableAttribute");

    /// Logic.
}
