How to write Null character in TextBox?

Hi frinend,
This will work for you.
string str = "trj\\0klk";
textBox1.Text = str.ToString();
 
But I dont know it's what you want.
 
If this helps, please accept my answer.

Hi,
\\0 and \0 are very different, when you put @ before the string, the textbox will read null character as two characters: backslash and '0' characters, and that 's not what i want.

Thanks.

Hi,

Try this

string myValue = @"example\0next";

TextBox1.Text = myValue;

// Should show exaclty "example\0next"

Thank you a lot for your fast response, but the question does not answer my question, because i do not need to replace the null character "\0" by space character, i need null character to be in the TextBox even it appears as a square which usually comes instead of the controls characters. The appearing of "\0" (or as a square) in Textbox is very important to me, because i have an application does a modern encryption for a plaintext and retrieve the ciphertext, in order to be sure of that the decryption work well, i copy the ciphertext from the TextBox then i past it in another TextBox embedded in the decryption application, so i can not neglected any character in the plaintext, therefore i want each character to be red in the TextBoxes even it is a control character.

Thanks.
My best wishes.

Hi,

const string NULL = " ";
string theValue = "example\0next"

TextBox1.Text = theValue.Replace("\0",NULL);

// This Sample will show "example next"

This will solve your problem. Set the NULL variable with the char you want to represent in the control.
