Value was either too large or too small for an Int32

Question

User-542418535 posted

I know this is a dumb question but please bear with with me. I have a textbox called txtTelNumber which will display the phone number entered into the textbox. When running the program, it stopped at this line:

int TelNumber = Int32.Parse(txtBoxTelNumber.Text);

and showed this error: "Value was either too large or too small for an Int32."

I am puzzled of this. The txtTelNumber max length is set to 10.

Why do you want to save phone number in integer variable? Maximum for int is 2147483647, so it cannot be used for 10-digit numbers bigger than 2147483647.

Yeah that totally makes sense. Which data type would be best to store a phone number in?

string for c#, varchar(10) for your database.

If you have international phone numbers, you will need more than 10 string characters since international numbers also need a country code.

In this case, the txtTelNumber max length must be changed too.

try this,

long TelNumber = Int64.Parse(txtBoxTelNumber.Text);
