然而，我总感到非常遗憾，既然泛型的where约束中可以使用new()，那么，为何不能提供带参的构造函数约束呢？例如这样的实现：
public static class ThrowHelperGeneric<TCustomException>
where TCustomException : ApplicationException, new(), new(string), new(string, Exception)
{
public static TCustomException ThrowCustomException(string message)
{
LogService.Error(message);
throw new TCustomException(message);
}
public static TCustomException ThrowCustomException(string message, Exception innerException)
{
LogService.Error(message, innerException);
throw new TCustomException(message, innerException);
}
}
where TCustomException : ApplicationException, new(), new(string), new(string, Exception)
{
public static TCustomException ThrowCustomException(string message)
{
LogService.Error(message);
throw new TCustomException(message);
}
public static TCustomException ThrowCustomException(string message, Exception innerException)
{
LogService.Error(message, innerException);
throw new TCustomException(message, innerException);
}
}
不知在将来的C#版本中可否提供这样的泛型支持呢？莫非，实现这样的语法还存在相当的难度？
