帮助数组 [英] Help with array

问题描述

我想从文本框中输入的路径中提取文件名

这样做：


string sFile = File1。值;

string [] sArray = sFile.Split（new char [] {''/''}）;

sFile = sArray.GetValue（sArray.GetUpperBound（ 0））;


但是，我收到以下错误：

编译器错误消息：CS0029：无法将类型''object'隐式转换为

''字符串''


我无法弄清楚如何纠正这个问题。有人可以帮我吗？


谢谢！

一个好的起点。

I''m tyring to extract the file name from a path entered in a text box by
doing this:

string sFile = File1.Value;
string[] sArray = sFile.Split(new char[] {''/''});
sFile = sArray.GetValue(sArray.GetUpperBound(0));

However, I get the following error:
Compiler Error Message: CS0029: Cannot implicitly convert type ''object'' to
''string''

I can''t figure out how to correct this. Can someone help me here?

Thanks!

推荐答案

sFile =（string）sArray.GetValue（sArray.GetUpperBound（0））;
GetValue返回一个对象。另外你应该使用索引器[]来

以类型安全的方式访问数组的元素。

sFile = (string)sArray.GetValue(sArray.GetUpperBound(0)); GetValue returns an object. Alternative you should use the indexer [] to
access the elements of the array in a type-safe manner.

最简单的办法是避免使用Array方法，只需使用

正常即可。访问数组的方式：


sFile = sArray [sArray.Length-1];


要更正现有代码，您只需添加一个演员阵容

虽然。

如果回复小组，请不要给我发邮件

The easiest thing to do is avoid using the Array methods, and just use
the "normal" way of accessing arrays:

sFile = sArray[sArray.Length-1];

To correct your existing code, you could just add a cast to string
though.
