如何获取Shell32.Folder.GetDetailsOfvItem,iColumn方法的最大索引max iColumn?

问题描述

目前,我得到的GetDetailsOf属性列表如下:

using Shell32;//Add reference > .COM > Type Libraries > Microsoft Shell Controls and Automation

//....
var shell = new Shell();
var objFolder = shell.NameSpace(SS.ExeFolder);//SS.ExeFolder = this exe folder path

var arrExistCols = new List<string>();
var existCol = string.Empty;
for (var i = 0; i < short.MaxValue; ++i)
{
    existCol = objFolder.GetDetailsOf(null,i);
    if (string.IsNullOrEmpty(existCol))
        break;
    arrExistCols.Add(existCol.toupper());
}

但是在this case中:163处的索引为空,因此我的上面的代码将从163开始丢失。

因此,也许我只将幻数310用于最大索引,但这并不可靠,如果在其他计算机上,最大索引为320,该怎么办? 那有什么办法可以获取GetDetailsOf的最大索引?
