Mar*_*ark 2 c# arrays foreach text-files winforms
我正在通过C#中的Windows窗体选择带有文件夹路径的文本文件,并收集有关每个路径的信息.此时,我可以导入文件并仅显示文本文件中的第二个路径,但没有关于该文件夹的信息.这是我的代码:
private void btnFilePath_Click(object sender, EventArgs e)
{
//creating a stream and setting its value to null
Stream myStream = null;
//allowing the user select the file by searching for it
OpenFileDialog open = new OpenFileDialog();
open.InitialDirectory = "c:\\";
open.Filter = "txt files (*.txt)|*.txt";
open.FilterIndex = 2;
open.RestoreDirectory = true;
//if statement to print the contents of the file to the text box
if (open.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = open.OpenFile()) != null)
{
using (myStream)
{
txtFilePath.Text = string.Format("{0}", open.FileName);
if (txtFilePath.Text != "")
{
lstFileContents.Text = System.IO.File.ReadAllText(txtFilePath.Text);
//counting the lines in the text file
using (var input = File.OpenText(txtFilePath.Text))
{
while (input.ReadLine() != null)
{
//getting the info
lstFileContents.Items.Add("" + pathway);
pathway = input.ReadLine();
getSize();
getFiles();
getFolders();
getInfo();
result++;
}
MessageBox.Show("The number of lines is: " + result, "");
lstFileContents.Items.Add(result);
}
}
else
{
//display a message box if there is no address
MessageBox.Show("Enter a valid address.", "Not a valid address.");
}
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read the file from disk. Original error: " + ex.Message);
}
}
}

我在想使用foreach将每一行复制到一个变量,或者将每一行放入一个数组中并循环遍历它以收集信息.
任何人都可以告诉我哪个是最合适的,所以我可以去MSDN并为自己学习,因为,我更愿意学习它而不是给出代码.
谢谢!

剧透警报,我会这样做:
string[] lines = null;
try
{
lines = File.ReadAllLines(path);
}
catch(Exception ex)
{
// inform user or log depending on your usage scenario
}
if(lines != null)
{
// do something with lines
}
