.Net: better equiv for " " (space character)?

Question

I am using a string builder as part of a logging process. my seperator character I am using is " ". How can I output this char in a more effective way than simply " ".

For example:

sb.Append(" ");

Or this this the acceptable way to do this?

Thanks in advance

Answer 1

This is perfectly fine.

However, you may want to raise the abstraction level a bit:

public static StringBuilder AppendWithSeparator(this StringBuilder sb, string value)
{
    sb.Append(value);
    sb.Append(" ");

    return sb;
}

Answer 2

If it is a single character better use sb.Append(' ');

Answer 3

If you're worried that it's going to create a new string object each time, stop worrying. The compiler will optimize it to use the same string object on every call.

Answer 4

You are probably thinking there is an alternative like string.Empty for "". But there is no such thing, so using " " is ok.

Answer 5

You may be better having a const char seperator = ' ' defined somewhere. Then using sb.Append(seperator)

That would make the code more maintainable if at a later point you decide to use (eg) comma seperation.
