如何使用未指定数量的参数构建一个方法C＃

Question

This is my code:

    private static string AddURISlash(string remotePath)
    {
        if (remotePath.LastIndexOf("/") != remotePath.Length - 1)
        {
            remotePath += "/";
        }
        return remotePath;
    }

But I need something like

AddURISlash("http://foo", "bar", "baz/", "qux", "etc/");

If I recall correctly, string.format is somehow like that...

String.Format("{0}.{1}.{2}.{3} at {4}", 255, 255, 255, 0, "4 p.m.");

Is there something in C# that allows me to do so?

I know I could do

private static string AddURISlash(string[] remotePath)

but that's not the idea.

If this is something in some framework can be done and in others not please specify and how to resolve it.

Thanks in advance

Answer 1

I think you want a parameter array :

private static string CreateUriFromSegments(params string[] segments)

Then you implement it knowing that remotePath is just an array, but you can call it with:

string x = CreateUriFromSegments("http://foo.bar", "x", "y/", "z");

(As noted in comments, a parameter array can only appear as the last parameter in a declaration.)

Answer 2

You can use params, which lets you specify any amount of arguments

private static string AddURISlash(params string[] remotePaths)
{
    foreach (string path in remotePaths)
    {
        //do something with path
    }
}

Note that params will impact the performance of your code, so use it sparingly.

Answer 3

Try

private static string AddURISlash(params string[] remotePath)

That will allow you to pass a string[] as a number of separate parameters.

Answer 4

This might be what you're looking for (note the params keyword):

private static string AddURISlash(params string[] remotePath) {
    // ...
}
