簡潔版本：將參數(shù)用引號引起來并轉(zhuǎn)義\和是否足夠"？代碼版本我想string[] args使用ProcessInfo.Arguments 將命令行參數(shù)傳遞給另一個進程。ProcessStartInfo info = new ProcessStartInfo();info.FileName = Application.ExecutablePath;info.UseShellExecute = true;info.Verb = "runas"; // Provides Run as Administratorinfo.Arguments = EscapeCommandLineArguments(args);Process.Start(info);問題是我將參數(shù)作為數(shù)組獲取，必須將它們合并為單個字符串?？梢栽O(shè)計一個參數(shù)來欺騙我的程序。my.exe "C:\Documents and Settings\MyPath \" --kill-all-humans \" except fry"根據(jù)這個答案，我創(chuàng)建了以下函數(shù)來轉(zhuǎn)義單個參數(shù)，但是我可能錯過了一些東西。private static string EscapeCommandLineArguments(string[] args){ string arguments = ""; foreach (string arg in args) { arguments += " \"" + arg.Replace ("\\", "\\\\").Replace("\"", "\\\"") + "\""; } return arguments;}這足夠好還是有任何框架功能呢？

我也遇到這個問題。我沒有解析args，而是采用了完整的原始命令行并修剪了可執(zhí)行文件。即使不需要/未使用，這也具有在呼叫中保留空格的額外好處。它仍然必須在可執(zhí)行文件中追逐轉(zhuǎn)義符，但這似乎比args容易。
var commandLine = Environment.CommandLine;
var argumentsString = "";
if(args.Length > 0)
{
// Re-escaping args to be the exact same as they were passed is hard and misses whitespace.
// Use the original command line and trim off the executable to get the args.
var argIndex = -1;
if(commandLine[0] == '"')
{
//Double-quotes mean we need to dig to find the closing double-quote.
var backslashPending = false;
var secondDoublequoteIndex = -1;
for(var i = 1; i < commandLine.Length; i++)
{
if(backslashPending)
{
backslashPending = false;
continue;
}
if(commandLine[i] == '\\')
{
backslashPending = true;
continue;
}
if(commandLine[i] == '"')
{
secondDoublequoteIndex = i + 1;
break;
}
}
argIndex = secondDoublequoteIndex;
}
else
{
// No double-quotes, so args begin after first whitespace.
argIndex = commandLine.IndexOf(" ", System.StringComparison.Ordinal);
}
if(argIndex != -1)
{
argumentsString = commandLine.Substring(argIndex + 1);
}
}
Console.WriteLine("argumentsString: " + argumentsString);
