Remove the last three characters from a string

Question

I want to remove last three characters from a string:

string myString = \"abcdxxx\"; 

Note that the string is dynamic data.

Answer 1

Probably not exactly what you're looking for since you say it's "dynamic data" but given your example string, this also works:

? "abcdxxx".TrimEnd('x');
"abc"

Answer 2

Remove the last characters from a string

TXTB_DateofReiumbursement.Text = (gvFinance.SelectedRow.FindControl("lblDate_of_Reimbursement") as Label).Text.Remove(10)

.Text.Remove(10)// used to remove text starting from index 10 to end

Answer 3

items.Remove(items.Length - 3)

string.Remove() removes all items from that index to the end. items.length - 3 gets the index 3 chars from the end
