Testing Void in Visual Studio 2010 - testing

Question

I have single project(c#) and have the following codes.
Everything is working fine. But I just want to know
how to test it and view the result in Visual Studio 2010.
I am classic asp developer and always use Response.end() to get result. but no idea how to do it in c# project. Thanks.
public static string ApplicationLocationList()
{
GetApplicationLocationListTableAdapter getApplicationLocationListTableAdapter = new GetApplicationLocationListTableAdapter();
DataTable dtgetApplicationLocationListTableAdapter.GetApplicationLocationListData(Library.MovieClass.saveApplicationID);
if (dt.Rows.Count > 0)
{
StringBuilder sb = new StringBuilder();
for (int i = 0; i < dt.Rows.Count; i++)
{
string cityList = dt.Rows[i]["City"].ToString();
string stateList = dt.Rows[i]["State"].ToString();
sb.Append(cityList + "," + stateList + System.Environment.NewLine);
}
return sb.ToString();
}
else
{
return string.Empty;
}
}

Answer 1

Judging by your reference to the Response object, I'm guessing this is an ASP.NET project. If you want to see the contents of sb on the page, you could try the following:
Response.Write(sb.ToString());
Response.Flush();
That should write the contents of the StringBuilder to the Response buffer & the Flush() method should send it down to the client page.
If you want to see only the empty string returned, you could just omit the Write() method & just Flush() the response, which should show you only a blank page after the postback.

I'm assuming that this is an ASP.NET application, in which case you want to use System.Web.HttpApplication.CompleteRequest as an equivalent to Response.End, and Response.Write(sb.ToString()); before the return sb.ToString();.
If it's a console application, then use System.Diagnostics.Debug.WriteLine(sb.ToString()); in the same place.
