The method of converting C # ASP to int is useful

A lot of beginners in the C # or. NET development always encounter some small problems, how to know if the character can be int type here I wrote a small function for your reference only:

<summary>///        judgment is not int///</summary>//        <param name= "str" > Received string </param>        //<returns></returns> public bool Isint (string str)        {            try            {                //string to be received here                int a = Convert.ToInt32 (str);                True if the conversion is returned successfully, it  can be converted to the INT type                return true;            Catch             {                //If the conversion of type int fails returns FALSE, the string contains non-numeric characters so it cannot be converted to int type                return false;            }            When using this function,   you only need to determine whether the return is true or false        }
