如何使用Toarray（）" System.Collections.Generic.Dictionary"

问题描述

IList<Dictionary<string, object>> bookmarks = SimpleBookmark.GetBookmark(pdfReader);
           // var v = bookmarks.OfType <string>().ToArray();
           for (int i = 0; i < bookmarks.Count; i++)
           {




              MessageBox.Show(bookmarks[i].Values.ToArray().GetValue(0).ToString());

但它在转换中显示错误 Toarray



错误 - 'System.Collections.Generic.Dictionary< string，object> .ValueCollection'不包含'ToArray'的定义，也没有扩展方法'ToArray '接受第一个类型的参数



请帮忙。

But It showing error in conversion Toarray

Error -- "'System.Collections.Generic.Dictionary<string,object>.ValueCollection' does not contain a definition for 'ToArray' and no extension method 'ToArray' accepting a first argument of type "

Please Help.

推荐答案

Dictionary<string, object> d = new Dictionary<string, object>();
for (int ii = 1; ii < 10; ii++)
    d.Add((ii * 111).ToString(), ii * 11);
Console.WriteLine(d[d.Keys.ToArray()[0]]);
Console.WriteLine(d.Values.ToArray()[0]);
IList<Dictionary<string, object>> bookmarks = new List<Dictionary<string, object>>();
bookmarks.Add(d);
int i = 0;
Console.WriteLine(bookmarks[i].Values.ToArray().GetValue(0).ToString());

编译并运行完美...



那么我在做什么呢和你不一样？

And it compiled and ran perfectly...

So what am I doing that is different from you?
