逐行遍历文本文件c＃

Question

Basically this is the code I currently have;

public async void readTextFile()
{      
    try {
        StorageFolder folder = KnownFolders.VideosLibrary;
        StorageFile storageFile = await folder.GetFileAsync("students.txt");

        string text = await Windows.Storage.FileIO.ReadTextAsync(storageFile);

        } catch (Exception e) {
            the_name.Text = "{0} Exception caught." + e;
        }
    }
}

The text file has a list of students that is laid out like this

Student Name|false

Student Second|false

With the names of 10 students and the word false to specify whether they've taken the test in the app, if they have taken it false reverts to true.

What my question is. How can I iterate through every line in that text file and store the one that has been typed in the textbox in a variable?

Just to note: I'm creating a windows desktop store application

Thanks in advance!

代替使用ReadTextAsync方法，可以使用ReadLinesAsync方法，然后遍历结果并分割管道字符以查找所需内容。
