pass n params like String.Format()

[sklett]

I have a simple debug and logging class and I would like to be able to send
a non-formatted string to my various printing methods, much like
string.format().

I have tried to implement this like so:
public void PrintDebugError(string format, object[] parameters)

{

string buff = string.Format(format, parameters);

m_outputBox.Items.Add(buff);

}


Then when calling it like this:
int someValue = 666;

m_debug.PrintDebugError("Loaded {0} shots from the database...", someValue);



I get the obvious error:
The best overloaded method match for 'CAppDebug.PrintDebugError(string,
object[])' has some invalid arguments


So looking at the string.format(), how do they do it? If I create an object
array, then store the int into the array and pass that, it works fine.
I guess what I'm looking for is a way to specify n parameters..

Any ideas?

Hi sklett,

Use the params keyword.

For example:
public void Format(params string[] args)

Hello sklett,

take a look at the params keyword.

public void PrintDebugError(string format, params object[] parameters)...

Look up the "params" keywword. If you define your method as
public void PrintDebugError(string format, params object[] parameters)
then it should work.
