如何从一个方法分别返回两个字符串而无需追加？

Question

I have method that will receive a string input(with message & mode name) and the method will separate the string input in to two strings(1.message 2.mode name) according to separator. but i need to return this separated two string at a time.please provide me a good way to do this.can i use "out" and return in one method? if yes, please tell me any links to do the out parameter. (or) any good way if you have.

Answer 1

You can use out parameters:

string myMethod(string input, out secondOutput)
{
   secondOutput="bla";
   return "xyz";
}

you can also use 2 out parameters:

void myMethod(string input, out firstOutput, out secondOutput)
{
   firstOutput="bla";
   secondOutput = "xyz";
}

Or like others suggested and I think is preferrable most of the time, using an array:

string[] myMethod(string input)
{
   return new string[] {firstOutput, secondOutput);
}

If you can tell us what the method is for we might help you choosing the best alternative.

为什么不将2个字符串放入Array并返回该Array？
