I want to get insensitive case entering the text from the textbox1.text. In Turkish language some letters like I,i cause problem. When I enter either small letter i or capital letter I, I want to get result.

Accepted answer

string userInput = textBox1.Text.ToLower(new CultureInfo("tr-TR"));

Try below code:

using System.Globalization;

// Get the input text from the textbox
string input = textbox1.Text;

// Create a CultureInfo object for the Turkish culture
CultureInfo turkishCulture = new CultureInfo("tr-TR");

// Compare the input text to "some text" using a case-insensitive comparison
if (string.Compare(input, "some text", turkishCulture, CompareOptions.IgnoreCase) == 0)
{
    // Do something if the input matches the desired text
}

Thanks

I tried your proposal but it doesn't work if the first letter begins with the capital letter "I".
