string.Format and string adding spaces

Question

With both string.Format and using string concatenation is adding spaces in my string, which is in turn making my Test methods fail. Here is my ToString() method:

public override string ToString()
    {
        return string.Format("First name: {0}, Last name: {1}, Age: {2}", FirstName, LastName, Age);

    }//end of ToString()

I also tried this and got the same output:

public override string ToString()
    {
        return "First name: " + FirstName  + ", Last name: " + LastName + ", Age: " + Age;

    }//end of ToString()

There is no space after the place holder, before the comma but when run this is the output:

First name: Jen , Last name: Doe , Age: 26

It puts a space after the placeholder, Why is this? how do I stop it

Are you sure that this is not simply a case of all the names having an extra space at end? — Xaver Kapeller

FirstName.Trim()

The variables might contain spaces.

You know I was already using Trim() so at first I thought "no way I am trimming the whitespace, but then ... I looked at the implicit operator and realized when looping over the string it was adding the whitespace. duh?
