How to pass values to c# parameters starting with @

Question

Trying to pass the values but not making progress.

Scenario : Have a public constant string as below.

public const string ImageFile = @"http://xyz.com/scom/{0}?type={1}&wid={2}";

I will then get the relevant values required for 0,1,2 that is required for above.

Question is how do I pass the values I have for 0,1,2 to the above const string?

My end result should be something like

string mySTring = "http://xyz.com/scom/123?type=jpg&wid=200"

Please suggest.

Thanks.

How did you know the syntax for string.Format (i.e. {0}) without knowing about string.Format? — Kirk Woll

@KirlWoll - Methods like Console.WriteLine allow for composite formatting. In other words, string.format can be used implicitly in many if not most cases. Many developers can use string.format and never even know it. msdn.microsoft.com/en-us/library/txafckwd.aspx — P.Brian.Mackey

I once encountered a major performance issue because someone knew all about vfprintf, but had no idea sprintf existed... — zmbq

Using String.Format:

string ActualImageFile = String.Format(ImageFile, param1, param2, param3);

string.Format(@"http://xyz.com/scom/{0}?type={1}&wid={2}", param1, param2, param3);

Should do the trick.
