How to append string representation of a specified object to a instance

Question

I have a code like this:

StringBuilder systemCondition = new StringBuilder();
systemCondition.Append("^(");
systemCondition.Append(Regex.Escape(this.Class));
systemCondition.Append(" : ");
systemCondition.Append(Regex.Escape(this.Instance));
systemCondition.Append(")$");
m_afc.QualifiedInstanceFilter = systemCondition.ToString();

Can any body tell me whats wrong here? Then what about this code

You are returning whole different stuff, that is why you see different string. You didn't optimize the code, you changed the logic itself. — user447356

If you just want more elegant code in one line, why not this?

m_afc.QualifiedInstanceFilter = string.Format("^({0} : {1})$", Regex.Escape(this.Class), Regex.Escape(this.Instance));

What about the code? Don't know, you didn't really ask any question. String is totally fine, StringBuilder should be used only when you append to the string in a loop or something like that.

ricky throwing code at us won't help. You have to explain what exactly is wrong.
