但我无法在我的代码中找到错误，因为它在手动输入到主机上的powershell时起作用，而.Save（）不带参数。你有什么想法吗？
答案 0 :(得分：0)
好的，而不是
command2 = command2 + string.Format(" ${1} = $shell.CreateShortcut(\"C:\\ClusterStorage\\Volume2\\test.lnk\"); ${1}.TargetPath = \"{0}\\_VMBackup\\{2}\\{1}\"; ${1}.Save();", backupDir, vm.Name, date);
尝试
command2 = command2 + string.Format(" $shortc = $shell.CreateShortcut(\"C:\\ClusterStorage\\Volume2\\test.lnk\"); $shortc.TargetPath = \"{0}\\_VMBackup\\{2}\\{1}\"; $shortc.Save();", backupDir, vm.Name, date);
command2 = "'" + command2 + "'"
这不起作用，也没有做很多其他事情。 基本上，问题是命令字符串传递给PowerShell执行的方式。 PowerShell将检查sting并尝试枚举所有变量。这不是理想的行为。试图将整个字符串用单引号括起来，但这并没有帮助。 最后，解决方案是使用PowerShell转义字符“`”来掩盖所有变量名称。
command2 = command2 + string.Format(" `$shortc = `$shell.CreateShortcut(\"C:\\ClusterStorage\\Volume2\\test.lnk\"); `$shortc.TargetPath = \"{0}\\_VMBackup\\{2}\\{1}\"; `$shortc.Save();", backupDir, vm.Name, date);
