代码的意思真的比看起来要简单得多。继续使用 ReSharper，我发现了以下内容:

string sNoteType;
var items = objSelection.Items;

var item0Selected = items[0].Selected;
string item3NotSelectedValue;
if (items[1].Selected)
{
    item3NotSelectedValue = item0Selected ? "LS " : "FD ";
}
else
{
    item3NotSelectedValue = item0Selected ? "LS " : string.Empty;
}

if (items[2].Selected)
{
    sNoteType = "OV ";
}
else
{
    if (items[5].Selected)
    {
        sNoteType = "EV ";
    }
    else
    {
        if (items[4].Selected)
        {
            sNoteType = "LT ";
        }
        else
        {
            if (items[3].Selected)
            {
                sNoteType = "BA ";
            }
            else
            {
                sNoteType = item3NotSelectedValue;
            }
        }
    }
}

由于 Jon 做了所有艰苦的工作，这里有一个编辑，我认为将其归结为本质。显然，您希望尽快围绕这段代码进行测试——因为我无法想象在解码这个怪物时不会犯一些错误，而自动重构只会让您到目前为止(不是很好，从样本的外观来看)放在这里):

var items = objSelection.Items;
string sNoteType = string.Empty;    
if (items[0].Selected && items[1].Selected) {
    sNoteType = "LS ";
} else if (items[1].Selected) {
    sNoteType = "FD ";
} else if (items[2].Selected) {
    sNoteType = "OV ";
} else if (items[3].Selected) {
    sNoteType = "BA ";    
} else if (items[4].Selected) {
    sNoteType = "LT ";
} else if (items[5].Selected) {
    sNoteType = "EV ";
}
