Sectary

Do you only want to remove the last char if blank, or all trailing whitespace? – Semaphore

Answer 1

Specific for one space character:

if(MyString.EndsWith(" "))
    MyString = MyString.Substring(0, MyString.Length - 1);

or for any whitespace

MyString = MyString.TrimEnd();

Note typo: should be .Substring, not SubString. – Oberammergau

Answer 4

Use special designed for it functions Trim, TrimStart, TrimEnd:

var trimmedString = "this is my string with space at the end ".TrimEnd();

Annulate

Just to be clear, this will remove ALL whitespace from the front and the end of the string, not just a single space from the end. – Briefs

Updated to TrimEnd function :). Thanks. – Annulate

Answer 5

string someString = "i will have some blank space at the end    ";
someString = someString.Trim(); //blank space now removed

It's worth noting that this will also remove blank spaces at the start of a string also

Answer 6

You can use a Trim function with a char array as parameter to remove empty spaces and any other unwanted chars:

var formattedString = "formatted, but with empty values, , .";
var trimmedString = formattedString.TrimEnd(new char[] { ' ', ',', '.'});
// result = "formatted, but with empty values"

Answer 7

another code for check the last char of a string is a blank char:

string text = "hello  ";
bool isBlank = text[text.Length -1].ToString().Trim().Length > 0 ? false : true;
