C#: Evaluate C# Code (Eval Function)

It is function to give you a lot of chance such as convert string to object.

// Eval > Evaluates C# sourcelanguage

public static object Eval(string sCSCode) {

CSharpCodeProvider c = new CSharpCodeProvider();
ICodeCompiler icc = c.CreateCompiler();
CompilerParameters cp = new CompilerParameters();

cp.ReferencedAssemblies.Add("system.dll");
cp.ReferencedAssemblies.Add("system.xml.dll");
cp.ReferencedAssemblies.Add("system.data.dll");
cp.ReferencedAssemblies.Add("system.windows.forms.dll");
cp.ReferencedAssemblies.Add("system.drawing.dll");

cp.CompilerOptions = "/t:library";
cp.GenerateInMemory = true;

StringBuilder sb = new StringBuilder("");
sb.Append("using System;\n" );
sb.Append("using System.Xml;\n");
sb.Append("using System.Data;\n");
sb.Append("using System.Data.SqlClient;\n");
sb.Append("using System.Windows.Forms;\n");
sb.Append("using System.Drawing;\n");

sb.Append("namespace CSCodeEvaler{ \n");
sb.Append("public class CSCodeEvaler{ \n");
sb.Append("public object EvalCode(){\n");
sb.Append("return "+sCSCode+"; \n");
sb.Append("} \n");
sb.Append("} \n");
sb.Append("}\n");

CompilerResults cr = icc.CompileAssemblyFromSource(cp, sb.ToString());
if( cr.Errors.Count > 0 ){
 MessageBox.Show("ERROR: " + cr.Errors[0].ErrorText,
    "Error evaluating cs code", MessageBoxButtons.OK,
    MessageBoxIcon.Error );
 return null;
}

System.Reflection.Assembly a = cr.CompiledAssembly;
object o = a.CreateInstance("CSCodeEvaler.CSCodeEvaler");

Type t = o.GetType();
MethodInfo mi = t.GetMethod("EvalCode");

object s = mi.Invoke(o, null);
return s;

}
