How to exit from a method manually?

Question

I have a query which returns a DataSet. After that I check whether records are available or not. If no records available I want to display error message, exit from the process and redirect to another page. Methods available in below the exiting method should not execute.

Here is the code I have so far.

ds = dba.loadEmpInfo(number, searchType, department);
        string appNumber = "";
        if (ds.Tables[0].Rows.Count > 0)
        {
            appNumber = ds.Tables[0].Rows[0]["Ref_no"].ToString();
            workDS = dba.workExp(appNumber, searchType);
        }
        else
        {
            WebMsgBox.Show("No Record relevant to this app number are available");

        }

What is this? WinForms? Console? ASP? Can you show more of the method? — Equalsk, Feb 03 '17 at 10:51
I think "redirect to another page" makes it clear it isn't a Winforms question. — Steve, Feb 03 '17 at 10:53

@TiMSchmelter, As in the code within the else part I want to display an error message, redirect to another page and finally to exit from the method (avoid the execution of other methods below this method) — Mike, Feb 03 '17 at 10:54

If you want to show Alert message from code behind use below syntax, ScriptManager.RegisterStartupScript(Control control, Type type,string key, string script,bool addScriptTags);

i.e, in the else part
{
ScriptManager.RegisterStartupScript(this, GetType(), "Alert", "alert('No Record relevant to this app number are available!');", true);
// Now Re-direct to the next page as you wish
Response.Redirect("yourPage.aspx");
}

This doesn't redirect to the page I want – Mike Feb 03 '17 at 11:11
The page you wish to Redirect is in same folder or its in different folder? – Dinesh Perumal Feb 03 '17 at 11:19
