One way is to have necessary C# code in a DLL and then call that DLL from your InstallScript with DotNetCoCreateObject. For example

set oObj = DotNetCoCreateObject("MyLibrary.dll", "MyLibrary.MyClass", "");
  
nRetVal = oObj.MyFunction();
if (nRetVal != 0 ) then
    szErrMsg = oObj.GetErrorMessage();
    SprintfMsiLog(szErrMsg);
endif;

The script editor in IS 2010 supports only InstallScript, but if you wish to use C#, you can use also Managed Code custom actions so that there's no need to use InstallScript to call your .NET assembly. That .NET assembly needs to be written in e.g. Visual Studio, though.

A better way is to write managed custom actions using WiX DTF. You then wire these custom actions us as standard MSI dll's without the need for InstallScript in the middle.
