c#字符串分割后，如何转换成10进制

比如字符串“aa 01 ff”，我要分别存储他们的十进制，就是170 1 255了
如何实现分割后的字符串aa,01,ff转换成10进制呢？
Convert.ToString(0xaa,10)这个需要前面的参数为十六进制，现在我前面的参数是字符，比如aa,ff如何操作

Convert.ToInt32("CC", 16)转成10进制，存为字符串就ok

string a ="aa"; MessageBox.Show(Convert.ToString(Convert.ToInt32(a,16), 16));

具体不怎么了解你的需求，如果你是想将"123"这个字符串转换为byte数组的话那就用 byte[] byts = new system.text.unicodeencoding().getbytes("123"); 这样byts这个byte数组变量就是"123"转换的byte数组 如果你是想将整个"123"数字字符串变成16进制再求这个16进制数的byte值的话 就可以这样写 byte byts=(byte)convert.toint32("123",16); 如果你想将字符串数组中的内容转换成单个的int值的再转成16进制，再转成byte数组的话，那帮你举个列子 1、2、3的16进制ascii码分别为31、32、33 byte[] byts=new byte[3]; byts[0]=(byte)0x31; byts[1]=(byte)0x32; byts[2]=(byte)0x33;

看看这个例子试试吧，从帮助文档上找的 using System; using System.Text; namespace Encoding_Examples { using System; using System.Text; class EncodingExample { public static void Main() { // Create an ASCII encoding. Encoding ascii = Encoding.ASCII; // A Unicode string with two characters outside the ASCII code range. String unicodeString = "This unicode string contains two characters " + "with codes outside the ASCII code range, " + "Pi (\u03a0) and Sigma (\u03a3)."; Console.WriteLine("Original string:"); Console.WriteLine(unicodeString); // Save the positions of the special characters for later reference. int indexOfPi = unicodeString.IndexOf('\u03a0'); int indexOfSigma = unicodeString.IndexOf('\u03a3'); // Encode the string. Byte[] encodedBytes = ascii.GetBytes(unicodeString); Console.WriteLine(); Console.WriteLine("Encoded bytes:"); foreach (Byte b in encodedBytes) { Console.Write("[{0}]", b); } Console.WriteLine(); // Notice that the special characters have been replaced with // the value 63, which is the ASCII character code for '?'. Console.WriteLine(); Console.WriteLine( "Value at position of Pi character: {0}", encodedBytes[indexOfPi] ); Console.WriteLine( "Value at position of Sigma character: {0}", encodedBytes[indexOfSigma] ); // Decode bytes back to a string. // Notice missing the Pi and Sigma characters. String decodedString = ascii.GetString(encodedBytes); Console.WriteLine(); Console.WriteLine("Decoded bytes:"); Console.WriteLine(decodedString); } } }
