BUG: Error message gives wrong information

Samser

I have run into a little error.

When having a DataSource field "Analysis.No" and type it wrong as e.g. "[Analysis.Na]" into a textbox I get this error:

wrote:

Text1: Error CS0103: Der Name 'Analysis' ist im aktuellen Kontext nicht vorhanden.

Translated e.g.

wrote:

Text1: Error CS0103: The Name 'Analysis' is not part of the current context.

Which is wrong. 'Analysis' is part of the current context, but 'Na' is not part of the 'Analysis' context.

I am using the .net Framework 4.0 demo of FastReport.

I learn something new from your question, "scripting".
If there is an error in the script, compiler generates error "..... is not part of the current context."

using System.CodeDom.Compiler;
using System.Reflection;


        private void button1_Click(object sender, EventArgs e)
        {
            Assembly myCode = CompileCode();
            if (myCode != null)
            {
                MethodInfo mi = myCode.GetExportedTypes().FirstOrDefault().GetMethod("AnotherMethod");
                try
                {
                    object result = mi.Invoke(new object(), null);
                    MessageBox.Show(result.ToString(), "Dynamic Method", MessageBoxButtons.OK);
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK);
                }                
            }
        }


        private Assembly CompileCode()
        {
            using (CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp"))
            {
                CompilerParameters parameters = new CompilerParameters();
                CompilerResults results = provider.CompileAssemblyFromSource(parameters, textBox1.Text);
                if (results.Errors.HasErrors)
                {
                    foreach (CompilerError err in results.Errors)
                    {
                        MessageBox.Show(err.ErrorText, "Compiler Error", MessageBoxButtons.OK);
                    }
                    return null;
                }
                return results.CompiledAssembly;               
            }     
        }

and textBox1.Text contains :

public class DynamicClass
{
    public static string DynamicMethod()
    {
        return "Hello World";
    }

    public static string AnotherMethod()
    {
        return "Another World";
    }
}
