public string ValidatePropPlant(Boolean valid, string Total1, string Total2)
   {
       valid = true;
       foreach (Control item in this.Controls)
       {
          ScheduleH = new SchedH();
          if (curr_PropPlantEquipTextBox.Text != ScheduleH.landBuildText.Text)
       {
          Total1 = curr_PropPlantEquipTextBox.Text;
           Total2 = ScheduleH.landBuildText.Text;
           valid = false;
       }
    }
        return valid;
        return Total1;
        return Total2;

Hmm, it ate my snippet :-(

You have a couple choices as outlined above. Here are examples using both the output parameters and a complex return type.

// option 1 output parameters

private void Validation_Click(object sender, EventArgs e)
{
	string Total1, Total2; 
	if (ScheduleF.ValidatePropPlant(out Total1, out Total2) == false)
	{
		MessageBox.Show("Total" + Total1 + "should be equal to" + Total2);
	}
} 
public bool ValidatePropPlant(out string Total1, out string Total2)
{
	bool RetVal = true;
	Total1 = Total2 = string.Empty; 
	foreach (Control item in this.Controls)

			Total2 = ScheduleH.landBuildText.Text;
			RetVal = false;
		}
	} 
	return RetVal;
} 

// option 2 complex return type
// called like
public struct ReturnType

	public bool Valid { get; set; }
	public string Total1 { get; set; }

	}
} 
public bool ValidatePropPlant()
{
	ReturnType RT = new ReturnType();
	RT.Valid = true;
