转换为foreach [英] Converting from for to foreach

问题描述

大家好，



我是.net的新手，我有一个需要编写foreach循环的情况，但我并不完全清楚但是我写道for循环。任何人都可以帮我转换下面的代码到foreach吗？



以下是我的代码：

Hi All,

I am new to .net and i have a situation where need to write the foreach loop but i am not aware of it exactly but i wrote for loop. Can anyone help me converting the below code to foreach?

Below is my code:

List<Int32> multiObject = ((List<Int32>)favoriteDocumentsField.Value);
     for (int index = 0; index < multiObject.Count; index++) {
          Int32 docID = multiObject[index];
          Console.WriteLine("Artifact: {0} Field: {1} Value: {2}", employee.ArtifactID, favoriteDocumentsField.Name + " Object " + index, docID);
     }

任何帮助都将不胜感激。



我尝试过：



我尝试在谷歌搜索。我得到了直接的FOREACH循环示例并且使用但没有得到从for到foreach的转换。

Any help would be appreciated.

What I have tried:

I tried searching in google. I got the direct FOREACH loop examples and used but didn't get the conversion from the for to foreach.

推荐答案

未经测试

Untested

List<Int32> multiObject = ((List<Int32>)favoriteDocumentsField.Value);
     foreach (int docID in multiObject) {
          Console.WriteLine("Artifact: {0} Field: {1} Value: {2}", employee.ArtifactID, favoriteDocumentsField.Name, docID);
     }

我已经放弃了从WriteLine写入索引值，因为它不再存在。如果你真的想要那个索引值，你最好把它留作for循环。你可以将索引作为自己的变量并在foreach中增加它，但是当你可以将它保持为for循环时，没有必要这样做。

I've dropped writing the index value from your WriteLine as it no longer exists. If you really want that index value you're better leaving it as a for loop. You could have index as its own variable and increment it inside the foreach, but there is not point in doing that when you can keep it as a for loop instead.
