To convert a hexadecimal string to a number Use the ToInt32 method to convert the number expressed in base-16 to an integer. The first argument of the ToInt32 method is the string to convert. The second argument describes what base the number is expressed in; hexadecimal is base 16. VB...
This example shows another way to convert a hexadecimal string to an integer, by calling the Parse(String, NumberStyles) method. C# Copy string hexString = "8E2"; int num = Int32.Parse(hexString, System.Globalization.NumberStyles.HexNumber); Console.WriteLine(num); //Output: 2274 The follo...
