整数到十六进制:

Int a = 72; 控制台。WriteLine(“{0:X}”);

十六进制到整型:

int b = 0xB76; Console.WriteLine (b);

十六进制:

string hex = intValue.ToString("X");

整数:

int intValue = int.Parse(hex, System.Globalization.NumberStyles.HexNumber)

Use:

int myInt = 2934;
string myHex = myInt.ToString("X");  // Gives you hexadecimal
int myNewInt = Convert.ToInt32(myHex, 16);  // Back to int again.

有关更多信息和示例，请参见如何:在十六进制字符串和数字类型之间转换(c#编程指南)。

打印十六进制值的整数与零填充(如果需要):

int intValue = 1234;

Console.WriteLine("{0,0:D4} {0,0:X3}", intValue);

整数到十六进制:

Int a = 72; 控制台。WriteLine(“{0:X}”);

十六进制到整型:

int b = 0xB76; Console.WriteLine (b);

int valInt = 12;
Console.WriteLine(valInt.ToString("X"));  // C  ~ possibly single-digit output 
Console.WriteLine(valInt.ToString("X2")); // 0C ~ always double-digit output
