Another question on String.Join

Ecbruck told me I could do the following which worked great. Now I'm trying to figure out how I can compare what's in allFolders with data entered in a textbox.

So, allFolders will contain something like  Folder1,Folder2

So then if the user enters something like Folder2 in the NewUploadFolderTextBox.Text I want to compare this with the contents of allFolders. Then what I'm going to do is say that if there's a match, don't insert the folder into the UploadFolder_TBL, otherwise if there's no match, insert the new folder in the UploadFolder_TBL. How would I compare though what's in the allFoldersArray to the text in the NewUploadFolderTextBox.

Thanks Again!

ecbruck:

Yes, use String.Join like this: 

System.Collections.Generic.List<string> folders = new System.Collections.Generic.List<string>();    foreach (DataRow dr in myDs1.Tables["UploadFolder"].Rows)  {  	folders.Add(dr["UploadFolderName"].ToString());  }    string allFolders = String.Join(",", folders.ToArray());
