It returns ArgumentNullException when its argument is null value.ĭim stringToInteger As Integer = Convert.ToInt32(text)Ĭonsole.WriteLine( "Convert string using Convert.ToInt32(string) : " & stringToInteger & vbLf) Int.Parse (string): It is faster then Convert.ToInt32 (string). It takes object as an argument and it does not through ArgumentNullException when its argument is null value. You can easily convert string to integer value by using Convert.ToInt32 (string) method or int.Parse (string) method both work similar but there is difference in both of them.Ĭonvert.ToInt32 (string): System namespace provide Convert class.
