我对 c# 相当陌生。我想实现一个接一个地删除多个注册表项，但是第一个键出现异常，之后代码停止删除其他键。我尝试了下面提到的代码，它适用于 if 块中的单个键

string[] keyArray = { @"Wow6432Node\CLSID",
            @"Software\Microsoft\Windows\CurrentVersion\Ext\Settings",
            @"Software\Microsoft\Windows\CurrentVersion\Ext\Stats",
            @"SOFTWARE\Classes\Wow6432Node\CLSID",
            @"SOFTWARE\Wow6432Node\Classes\CLSID",
            @"Wow6432Node\Microsoft\Code Store Database\Distribution Units",
            @"Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility",
            @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\ModuleUsage"
    };

foreach (var key in keyArray)
{
    try
    {

        RegistryKey myKey = Registry.ClassesRoot.OpenSubKey(key, true);
        if (myKey != null)
        {
            /*Cisco Secure Desktop*/
            myKey.DeleteSubKeyTree("{705EC6D4-B138-4079-A307-EF13E4889A82}");
            myKey.DeleteSubKeyTree("{F8FC1530-0608-11DF-2008-0800200C9A66}");
            myKey.DeleteSubKeyTree("{E34F52FE-7769-46CE-8F8B-5E8ABAD2E9FC}");
            /*Cisco Hostscan*/
            myKey.DeleteSubKeyTree("{F8FC1530-0608-11DF-2008-0800200C9A66}");
            myKey.DeleteSubKeyTree("{E34F52FE-7769-46CE-8F8B-5E8ABAD2E9FC}");
            /*Cisco AnyConnect Secure Mobility Client*/
            myKey.DeleteSubKeyTree("{55963676-2F5E-4BAF-AC28-CF26AA587566}");
            myKey.DeleteSubKeyTree("{CC679CB8-DC4B-458B-B817-D447B3B6AC31}");
        }
        else
            Console.WriteLine(string.Format("could not open key: {0}", key));
    }
    catch (Exception ex)
    {
        System.Diagnostics.Debug.WriteLine(
            string.Format("action {0} failed with\n{1}", key, ex.Message));

    }
  }

根据您的详细信息，您可以尝试以下代码

string[] keyArray = { @"Wow6432Node\CLSID",
                @"Software\Microsoft\Windows\CurrentVersion\Ext\Settings",
                @"Software\Microsoft\Windows\CurrentVersion\Ext\Stats",
                @"Wow6432Node\Microsoft\Code Store Database\Distribution Units",
                @"Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility",
                @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\ModuleUsage",
                @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\ModuleUsage",
        };

foreach (var key in keyArray)
{   
    try
    {
        RegistryKey myKey = Registry.ClassesRoot.OpenSubKey(key, true);
        if (myKey != null)
            myKey.DeleteSubKeyTree("{55963676-2F5E-4BAF-AC28-CF26AA587566}");
        else
            System.Diagnostics.Debug.WriteLine(string.Format("could not open key: {0}", key));
    }
    catch (Exception ex)
    {
        System.Diagnostics.Debug.WriteLine(
            string.Format("action {0} failed with\n{1}", key, ex.Message));
    }                
}

这也应该打印出一些错误信息。

根据您给出的评论ArgumentException(...)，您尝试打开/删除一个 {55963676-2F5E-4BAF-AC28-CF26AA587566} 不存在的子项！也许你应该看看Registry.OpenSubKey和DeleteSubKeyTree(..)

最后，我有更好的代码，经过大量努力后可以正常工作请让我知道是否有人可以做得更好

   namespace ConsoleApplication1
   {
    class Program
    {
    static void Main(string[] args)
    {
