How could I remove the last space character from a string in c#?

I split text from a text file and I have to compare 2 strings, one from a textbox and the other one from a text file from a specific line. That string from text has a space at the end and the comparison is always wrong. Here is the code. Thank you!

private void button1_Click(object sender, EventArgs e)
{
    Random r = new Random();

    t = r.Next(1,30);
    StreamReader sr = new StreamReader("NomenA1.txt");
    cuv = sr.ReadToEnd().Split('\n');

    string original = cuv[t];

    Random num = new Random();

    // Create new string from the reordered char array.
    string rand = new string(original.ToCharArray().
        OrderBy(s => (num.Next(2) % 2) == 0).ToArray());
    textBox2.Text = rand;
    button1.Visible = false;
    button2.Visible = true;

}

private void button2_Click(object sender, EventArgs e)
{

    button1.Visible = false;
    string a =Convert.ToString(textBox1.Text.ToString());
    string b = cuv[t];

    if (a == b)
    {
        MessageBox.Show("Corect");
        button1.Visible = true;
        button2.Visible = false;
    }
    else
    {
        MessageBox.Show("Mai incearca"); button1.Visible = false;
    }
}

You can use Regex to remove all last space:

string s = "name    ";
string a = Regex.Replace(s, @"\s+$", "");

or Trim() function for all both end space:

string s = " name   ";
string a = s.Trim();

or if you want to remove only one space from the end:

string s = "name ";
string a = Regex.Replace(s, @"\s$", "");

Have you tried .Trim()

String myStringA="abcde "; 
String myStringB="abcde"; 

if (myStringA.Trim()==myStringB) 
{
  Console.WriteLine("Matches"); 
} 
else 
{
  Console.WriteLine("Does not match");    
}

How could I remove the last character in a string

var s = "Some string ";
var s2 = s.Substring(0, s.Length - 1);

Alternatively a general solution is usually

var s3 = s.Trim(); // Remove all whitespace at the start or end
var s4 = s.TrimEnd(); // Remove all whitespace at the end
var s5 = s.TrimEnd(' '); // Remove all spaces from the end

Or a very specific solution

// Remove the last character if it is a space
var s6 = s[s.Length - 1] == ' ' ? s.Substring(0, s.Length - 1) : s;

What about :

string s = "name ";
string a = s.Replace(" ", "");

That seems pretty simple to me, right?
