问题描述

嗨
如果我有一个byte []数组，并且想在类似0x3130353030330353032的文本框中显示它，该怎么办?我知道如何获得它的实际值"10500502".但是我想知道如何获取C#byte []对象并将其显示为0x3130353030353053032，基本上与SQL在查询窗口中显示的方式相同.

谢谢

Hi
If I have a byte[] array and I want to display it in a textbox like 0x3130353030353032, how would I do this? I know how to get it''s actual value which is "10500502". but I want to know how to take the C# byte[] object and display it as 0x3130353030353032 basically the same way that SQL does it in a query window.

Thanks

推荐答案

myTextBox.Text="0x";
foreach(byte b in array)
{
  myTextBox.Text += b.ToString("X2");
}

如果数组相对较长，则可以考虑使用 StringBuilder :: Append方法 [ ^ ]，而不是String ''+=''运算符以获得更好的性能.

If you array is relatively long, you may consider using StringBuilder::Append method[^], instead of the String ''+='' operator for better performance.

class Program
{
    static void Main(string[] args)
    {
        byte[] myBytes = Encoding.ASCII.GetBytes("Hello World");
        Console.WriteLine(GetString(myBytes));
    }
    private static String GetString(byte[] myBytes)
    {
        StringBuilder builder = new StringBuilder();
        builder.Append("0x");
        Array.ForEach(myBytes, item => builder.Append(item.ToString()));
        return builder.ToString();
    }
}
