Question

所以，我有这个代码

        Process[] processesManager = Process.GetProcesses();
        List<ProcessInfo> temporaryProcessesList = new List<ProcessInfo>();
        for (int i = 0; i < processesManager.Length; ++i)
        {
            temporaryProcessesList.Add(new ProcessInfo(processesManager[i].ProcessName, processesManager[i].Id, TimeSpan.Zero, "Group"));
        }

        processesList = temporaryProcessesList.GroupBy(d => new {d.Name}).Select(d => d.First()).ToList();

此代码用于获取当前进程。然后我将这些过程添加到temporaryProcessesList。而不是简单的字符串＆＃34; Group＆＃34;我想根据进程名称设置属性。例如，如果进程名称为leagueoflegends.exe，那么我想将组设置为＆＃34; Games＆＃34;，如果它的devenv.exe我想将组设置为＆＃34;软件开发＆＃34;。

我的问题是，如何以最简单/最好的方式做到这一点？我正在考虑将字符串与字符串和枚举一起使用。并将ProcessName与字符串进行比较。但也许有更好的方法来做到这一点。

ProcessInfo是一个简单的类，包含4个属性和构造函数。

public class ProcessInfo
{
    private string Name { get; set; }
    private int Id { get; set; }
    private TimeSpan Time { get; set; }
    private string Group { get; set; }

    public ProcessInfo(string name, int id, TimeSpan time, string group)
    {
        Name = name;
        Id = id;
        Time = time;
        Group = group;
    }
}

Answer 1

使用字典是实现此目的的最佳方式：

var dictionary = new Dictionary<string, string>();
dictionary.Add("a.exe", "aGroup");
dictionary.Add("b.exe", "bGroup");

string val;
if (dictionary.TryGetValue(processName, out val))
    processInfo.Group = val;
else
    processInfo.Group = "Undefined Group";

Answer 2

也许这就是你要找的东西：

    # file: pyenv\lib\site-packages\cryptography\hazmat\backends\__init__.py
def _available_backends():
    global _available_backends_list

    if _available_backends_list is None:
        _available_backends_list = [
            ep.resolve()
            for ep in pkg_resources.iter_entry_points(
                "cryptography.backends"
            )
        ]

    # patch starts here
    if _available_backends_list is None or len(_available_backends_list) == 0:
        # backend 1
        try:
            from cryptography.hazmat.backends.commoncrypto.backend import backend as be_cc
        except ImportError:
            be_cc = None
        # backend 2
        try:
            from cryptography.hazmat.backends.openssl.backend import backend as be_ossl
        except ImportError:
            be_ossl = None
        # add any backends of your own

        _available_backends_list = [
            be for be in (be_cc, be_ossl) if be is not None
        ]
    # patch ends here

    return _available_backends_list

这种设计并不完美，但希望你能看到这个想法。您还可以将public class ProcessInfo { private string _name; private string Name { get { return _name; } set { _name = value; UpdateGroupName(); } } private int Id { get; set; } private TimeSpan Time { get; set; } private string Group { get; set; } private void UpdateGroupName() { Group = ProcessNames::GetGroupFromProcessName(Name); } public ProcessInfo(string name, int id, TimeSpan time) { Name = name; Id = id; Time = time; } } internal static class ProcessNames { private static Dictionary<string, string> _names; public static string GetGroupNameFromProcessName(string name) { // Make sure to add locking if there is a possibility of using // this from multiple threads. if(_names == null) { // Load dictionary from JSON file } // Return the value from the Dictionary here, if it exists. } }名称的更新移动到构造函数，但如果在构造之后设置属性，则不会更改Group名称。

此外，您可以使用Group和/或依赖注入来清理界面。 https://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged(v=vs.110).aspx
