Need a C# Expert to review code: I want to delete a single Wkstn obj from AD.

if (radioSingleObj.Checked)
            {
                if (textBoxSingle.Text == "")
                {
                    MessageBox.Show("You need to enter a workstation name", "Input Required", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
                }
                else
                {
                    string objectName = textBoxSingle.Text;
                    MessageBox.Show(objectName);
 
                    string strPath = "LDAP://OU=Workstations,OU=BAND,DC=Corp,DC=BankofAmerica,DC=Com";
                    DirectoryEntry entry = null;
                    entry = new DirectoryEntry(strPath);
                    DirectorySearcher wkstnSearcher = new DirectorySearcher(entry);
                    wkstnSearcher.Filter = "(&(objectClass=computer)(|(cn=" + objectName + ")))";
                    wkstnSearcher.ClientTimeout.Seconds.Equals(30);
                    SearchResult searchWkstn = wkstnSearcher.FindOne();
                    if (wkstnSearcher.CacheResults)
                    {
                        labelWkstnObjStatus.Text = "Workstation object was located";
                        entry.Properties["cn"].Remove(objectName);
                        entry.CommitChanges();
                        entry.Close();
                    }
                    else
                    {
                        labelWkstnObjStatus.Text = "Unabled to locate Workstation object";
                    }
                }
            }
