int.Parse(System.Globalization.NumberStyles.HexNumber); code example
Example 1: hex string to int c#
string hex = "142CBD";
// this returns 1322173
int intValue = int.Parse(hex, System.Globalization.NumberStyles.HexNumber);
Example 2: hex string to int c#
string prefixedHex = "0x142CBD";
// this works, and returns 1322173
int intValue = Convert.ToInt32(prefixedHex , 16);
