Solution 1

Every string has a contains method[^]. Just check for a comma using contains within the string.

Solution 3

You can check it on "TextBox1_Change" event like :

if(Text1.Text.IndexOf(",") >= 0)
{
// TODO : If Comma found in textbox string, what u want to do ?????
}
else
{
// TODO : If Comma not found in textbox string, what u want to do ?????
}

Solution 4

C#

if (textbox1.Text.Contains(',')
{
    // Comma exists
}
else
{
    // Comma is not existed
}
