C#中方法的多个输出数据类型 [英] multiple output data type for method in C#

问题描述

尊敬的朋友:

我想有一个具有两个输入和一个 两个不同的输出 的方法.

例如:

Dear friends:

I want to have a method that has two input and two different output.

For example:

private int , byte Nameofmethod (string s , int i)
{

}

我该怎么办?

Yours

How should I do that?

Yours

推荐答案

通常，我认为更好的方法是返回一个包含所需所有输出的对象.不确定，这可能是您正在寻找的更好的解决方案.

Generally what I consider a better way is to return an object that contains all of the outputs you need. That may be a better solution for what you are looking for, cannot be sure.

private struct ReturnedObject
{
    public ReturnedObject(string variable1, string variable2)
    {
        Variable1 = variable1;
        Variable2 = variable2;
    }
    public string Variable1;
    public string Variable2;
}

private ReturnedObject SomeMethod ()
{
    return new ReturnedObject("first value", "second value");
}

有一些例外，但是C#是一种面向对象的语言，应该使用对象.我也更喜欢对象作为参数，否则某些调用会变得很长.对此的理解就是我正在做类似TryParse

There are exceptions, but C# is an object oriented language and should be using objects. I also prefer objects as arguments, otherwise some calls can become very long. The exeception to this would be where I am doing something like TryParse

的事情，使用带有out关键字的参数:

Use parameters with the out keyword:

private void MyMethod(string s, int i, out int intResult, out byte byteResult)
