我尝试执行此代码:
private void Test(object sender, RoutedEventArgs e)
{
ProcessStartInfo start = new ProcessStartInfo("cmd",
"/c \"wbadmin start recovert -version:02/26/2014-17:38 -itemtype:File - items:C:\test\"");
int exitCode;
using (Process proc = Process.Start(start))
{
proc.ErrorDataReceived += cmd_Error;
proc.OutputDataReceived += cmd_DataReceived;
proc.WaitForExit();
exitCode = proc.ExitCode;
}
}
private void cmd_DataReceived(object sender, DataReceivedEventArgs e)
{
if (e.Data == null) return;
var source = Encoding.Unicode;
var target = Encoding.UTF8;
var sBytes = source.GetBytes(e.Data);
var tBytes = Encoding.Convert(source, target, sBytes);
var tString = Encoding.UTF8.GetString(tBytes);
Console.WriteLine(tString);
}
但我得到了这个字符串:“wbadmin 1.0 - ®≠·,‡”¨•≠,™Æ†≠§≠©,‡Æ™®†‡¢†Ê®® 我该如何解码这个字符串?

从cmd解析输出可能有点棘手,因为您的cmd有自己的代码页,通常等于系统的默认语言环境(您可以手动更改它,例如使用chcp命令)
阅读this了解详情。
重定向输出时,对我有用的方法(经过测试,同时使用wbadmin
)如下:
获取系统的默认语言环境:
[DllImport("kernel32.dll")]
public static extern int GetSystemDefaultLCID();
private static int GetCmdCodePage()
{
int lcid = GetSystemDefaultLCID();
var ci = System.Globalization.CultureInfo.GetCultureInfo(lcid);
return ci.TextInfo.OEMCodePage;
}
获取相应的编码:
Encoding enc = null;
try
{
enc = Encoding.GetEncoding(GetCmdCodePage());
}
catch (Exception)
{
enc = Encoding.GetEncoding(855); // the value for Cyrillic
}
设置流程的编码:
if (!File.Exists(Path.Combine(Environment.SystemDirectory, @"wbadmin.exe")))
{
Console.WriteLine("wbadmin.exe not found");
return;
}
Process pr = new Process();
ProcessStartInfo psi = new ProcessStartInfo(@"wbadmin.exe");
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.CreateNoWindow = true;
psi.UseShellExecute = false;
psi.Arguments = "/?"; // prints avaliable commands
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
psi.Verb = "runas";
psi.StandardOutputEncoding = enc;
psi.StandardErrorEncoding = enc;
pr.StartInfo = psi;
pr.Start();
pr.WaitForExit(1000);
string error = pr.StandardError.ReadToEnd();
if (!string.IsNullOrEmpty(error))
{
Console.WriteLine("error: " + error);
pr.Close();
pr.Dispose();
return;
}
string output = pr.StandardOutput.ReadToEnd();
pr.Close();
pr.Dispose();

你的代码看起来完全正确,但毫无意义。事实是C#字符串总是UTF-16,无论如何。您的cmd_DataReceived方法将UTF-16转换为字节数组,其中包含原始字符串的UTF-8表示形式,然后通过调用Encoding.UTF8.GetString(tBytes)将其转换回UTF-16。
看起来外部程序以未知编码(UTF-8?)向控制台写入内容,但接收到的cmd_DataReceived已经解码为UTF-16。
我认为,如果您真的想将您的字符串从UTF-8转换为UTF-16,那么您的代码应该是
private void cmd_DataReceived(object sender, DataReceivedEventArgs e)
{
if (e.Data == null) return;
var source = Encoding.Unicode;
var target = Encoding.UTF8;
var sBytes = source.GetBytes(e.Data);
var tString = Encoding.UTF8.GetString(sBytes);
Console.WriteLine(tString);
}
