String array Function

[sarabonn]

hallo,

I have a function which takes 2 values as input and i want to return that 2 values, so how should write the return statement to return 2 values of String array. I also i should retrieve these values in a button click event. here is my code.

public String newop(string userna,string pwd)
        {
           cwe_pro.GetFolderContentRequestType preq = new cwe_pro.GetFolderContentRequestType();
           cwe_pro.GetFolderContentReplyType pres = new cwe_pro.GetFolderContentReplyType();
            try
            {
                preq.depth = 0;
                preq.folderId = docid;
                ws.Url = "http://www.cwe-projects.eu/bscw/bscw.cgi";
                ws.Credentials = new System.Net.NetworkCredential(userna, pwd);
                pres = ws.GetFolderContent(preq);
                XmlDocument doc = new XmlDocument();
                doc.LoadXml(pres.folderContent);
                XmlNodeList ni = doc.GetElementsByTagName("dcterms:modified");
                st = ni[0].InnerText;
                if (st.Equals(lmod))
                {
 
                    MessageBox.Show("No modification In the File");
                    textBox3.Visible = false;
                    groupBox3.Visible = true;
 
                }
                else
                {
 
                    MessageBox.Show("Last modified by another user :" + st);
                    textBox3.Visible = false;
                    groupBox3.Visible = true;
 
 
                }
            }
            catch (Exception e1)
            {
                MessageBox.Show(e1.ToString());
 
                return;
            }
      }
 
this is my function and how should write the return statement that return a array of those two values username and pwd. i have retreive these 2 values usrname and pwd in button click event.
 
private void button3_Click(object sender, EventArgs e)
        {
}
 

sorry iam newbie to c# i dont know this simple task itself. any idea ?..

Thank you.

You could use "out" parameters. You declare two parameters and mark them with the keyword "out", then make sure you assign them before the end of the method:

       public void newop(string userna, string pwd, out string resultString1, out string resultString2)
       {
           // make sure you assign the results to the two Out parameters before the method exits
           resultString1 = result1;
           resultString2 = result2;
       }

You would then call the method like this:

 public void Test()
       {
           string result1;
           string result2;
           newop("user", "pass", out result1, out result2);
       }

Result1 and result2 now contain your return values.

Alternatively, if you really want, you can return the results in a generic list (or another collection type):

public List<string> newop(string userna,string pwd)
           {
               List<string> results = new List<string>();
               results.Add(string1);
               results.Add(string2);
               return results;
           }

The last return would need to be

return results;

The last return would need to be

return results;

Thanks r035198x, must have missed that. I've corrected the code sample.

No problem.
