How to mention string value that is not case sensitive

Adarsh Balachandran

Hi, I want to declare a string value in a WPF application.
Example:
private void button1_Click(object sender, RoutedEventArgs e)
{
if (textBox1.Text == "Name")
{
label1.Content = "This is " + textBox1.Text;
}
}
If the user enter NAME/ name/ Name the if condition should apply and give the corresponding output
ie. label1 should display This is Name/ NAME/etc.

Sorry I didnt put my question clearly. Please consider the below code as an example:

if (textBox1.Text == "Name")
        {
        label1.Content = "This is " + textBox1.Text;
        }

else
        {
        label1.Content = "This is not my " + textBox1.Text;
        }

If I enter name in the text box, it will satisfy only the else condition and will display This is not my name. Instead of that it has to display This is my name. That is the first if condition statement should work for names, Name, NAME, nAME, etc.

Why do you need an "if" condition to test the case of your TextBox1!

If TextBox1 should always be upper case or lower case for that matter, then all you need to do is

TextBox1.Text = textBox1.Text.ToUpper();

OR simply

label1.Content = "This is " + textBox1.Text.ToUpper();

try like this

if (textBox1.Text.ToUpper() == "NAME")
        {
            label1.Content = "This is " + textBox1.Text;
        }
