如何在 C# 中优化枚举赋值

Question

我有这个枚举

enum NetopScriptGeneratingCases
{
    AddLogMessages,
    AddLogErrors,
    AddLogJournal,
    AllLog = AddLogMessages | AddLogErrors | AddLogJournal,
    DoNothing
}

还有 UI 有 3 个复选框，所以根据选中的复选框，我必须生成可能的案例来完成一些工作。

NetopScriptGeneratingCases netopScriptGeneratingCases = NetopScriptGeneratingCases.DoNothing;

if (checkBoxAddAuditLog.Checked)
{
    netopScriptGeneratingCases = NetopScriptGeneratingCases.AddLogJournal;
}
else if (checkBoxAddErrorLog.Checked)
{
    netopScriptGeneratingCases = NetopScriptGeneratingCases.AddLogErrors;
}
else if (checkBoxAddLogMessages.Checked)
{
    netopScriptGeneratingCases = NetopScriptGeneratingCases.AddLogMessages;
}
else if (checkBoxAddAuditLog.Checked || checkBoxAddErrorLog.Checked)
{
    netopScriptGeneratingCases = NetopScriptGeneratingCases.AddLogJournal | NetopScriptGeneratingCases.AddLogErrors;
}
else if (checkBoxAddAuditLog.Checked || checkBoxAddLogMessages.Checked)
{
    netopScriptGeneratingCases = NetopScriptGeneratingCases.AddLogJournal | NetopScriptGeneratingCases.AddLogMessages;
}
else if (checkBoxAddErrorLog.Checked || checkBoxAddLogMessages.Checked)
{
    netopScriptGeneratingCases = NetopScriptGeneratingCases.AddLogErrors | NetopScriptGeneratingCases.AddLogMessages;
}
else if (checkBoxAddErrorLog.Checked || checkBoxAddLogMessages.Checked || checkBoxAddAuditLog.Checked)
{
    netopScriptGeneratingCases = NetopScriptGeneratingCases.AddLogErrors | NetopScriptGeneratingCases.AddLogMessages | NetopScriptGeneratingCases.AddLogJournal;
}


var modifiedFiles = NetopScriptGenerator.GenerateNetopScript(netopScriptGeneratingCases, netopFiles);

但我不确定这段代码是否正确...还有其他方法吗？

如评论中所述，默认情况下，编译器会为枚举提供一个递增的整数值，这不适合用作位标志。尝试修改您的定义如下：

[Flags]
enum NetopScriptGeneratingCases
{
        DoNothing = 0,
        AddLogMessages = 1<<0,
        AddLogErrors = 1<<1,
        AddLogJournal = 1<<2,
        AllLog = AddLogMessages | AddLogErrors | AddLogJournal
}

我会采用并像这样分配你的变量：

NetopScriptGeneratingCases netopScriptGeneratingCases = NetopScriptGeneratingCases.DoNothing;

if (checkBoxAddAuditLog.Checked)
{
    netopScriptGeneratingCases |= NetopScriptGeneratingCases.AddLogJournal;
}
if (checkBoxAddErrorLog.Checked)
{
    netopScriptGeneratingCases |= NetopScriptGeneratingCases.AddLogErrors;
}
if (checkBoxAddLogMessages.Checked)
{
    netopScriptGeneratingCases |= NetopScriptGeneratingCases.AddLogMessages;
}
