Give the string Metal_In I have to extract the Metal part
I'm doing the following now:
DropDownList ddl = ctrl as DropDownList;
if(ddl != null)
{
ddl.ID = ddl.ID.Split('_')[1].ToString();
}
-
I think I managed to extract what the OP meant with my last edit.Isak Savo– Isak Savo2012-11-02 07:28:07 +00:00Commented Nov 2, 2012 at 7:28

instead of index 1 use index 0 (it can be done in a better way). Also you don't need ToString at the end as it is already a string.
dl.ID = ddl.ID.Split('_')[0].ToString();
You may check for array length before using index and .ToString
string[] tempArray = ddl.ID.Split('_');
if(tempArray.Length > 0)
ddl.ID = tempArray[0];
ddl.ID.Split('_')[1] will give you the 2nd part of the string which is In. Remember the array index starts with 0

With the string Metal_In, call Split ( broken out example below ).
string[] elems = ddl.ID.Split('_');
// elems contains two elements
// 0 - Metal
// 1 - in
To get the value of Metal, use subscript 0 to get the first element.
string firstPart = elems[0];

Since it can be assumed that Metal word exists in original string,
var item = ddl.Id.Split('_)[0]
Otherwise go with Habib's answer.

You can use FirstOrDefault, it will handle the array issues.
ddl.ID = ddl.ID.Split('_').FirstOrDefault();
It will return null in case of empty array.
