Determine Empty Checkbox List

[Stuart Shay]

Hello All

I have a ASP.NET 2.0 checkbox list, the problem is when 0 items are checked
I am unable to determine if the list is empty
//Determine Checked Roles
CheckBoxList ckUserRoleList =
gvUserList.Rows[e.RowIndex].FindControl("c kUserRoleList") as CheckBoxList;
StringBuilder oStringBuilder = new StringBuilder() ;
foreach (ListItem li in ckUserRoleList. Items)
{
if (li.Selected == true) {
oStringBuilder. AppendFormat("{ 0},", li.Text);
}
}
if (oStringBuilder .Length != 0)
oStringBuilder. Remove(oStringB uilder.Length - 1, 1);

string[]userRoleList = (oStringBuilder .ToString().Spl it(new char[]
{','}));
/**** Empty Values are NOT Correctly Evaluated ****/

//Add New Roles for Selected User
if (userRoleList.L ength != 0)
{
Roles.AddUserTo Roles(userName, userRoleList);
}
