You may enumerate parameters in a report this way:

foreach (ParameterField field in reportDocument1.ParameterFields)
{
    MessageBox.Show(field.Name);
    MessageBox.Show(field.ParameterValueType.ToString());
}

You may set parameter values like so:

reportDocument1.ParameterFields["Project_Code"].CurrentValues.AddValue("100");
