Is there a function the the .Net framework that can evaluate a numering expression contained in a string and return the numeric result? IE: string mystring = "3*(2+4)"; int result = EvaluateExpression(mystring); Console.Writeln(result); prints 18. Is there a standard framework function that you can replace my EvaluateExpression with...
Suppose the user inputs an infix expression as a string? What could be the easiest ( By easiest I mean the shortest) way to evaluate the result of that expression using C language?

Hi all! I'm using MSBuild to customize the build process of Visual Studio, WiX, SandCastle, ... projects. To keep it as generic as possible I'd like to use text files defining some 'project specific' settings, like where the files should be loaded from, which custom executables to run and so on.
