C# windows form login form not detect capital and small letters ?

Hello NURU,

You can modify the code to perform a case-insensitive comparison. Use the string method “ToLower()” or “ToUpper()” on both the input and the stored username and password values before comparing them.

Example:

string username = txtUsername.Text.ToLower();
string password = txtPassword.Text.ToLower();
if (username == "admin" && password == "password")
{
	//successful
}
else
{
	//failed
}

Thanks
