Solution 2

You can also use Contains property which is used to returns a value indicating whether the specified String object

bool res =textBox1.Text.Contains("your Value"); // res will contain true if values is present

Is this what you are looking for

C#

//assuming a textbox named textbox1

int anInteger;
anInteger = Convert.ToInt32(textBox1.Text);//get the text as an integer

//or 
anInteger = int.Parse(textBox1.Text); //try to parse the value as an integer

another method is possibly

var match = textBox1.Text.IndexOfAny("1234567890".ToCharArray()) != -1
