我正在使用C#的Windows表单选择文本文件并获取有关每个路径的信息。目前,我可以导入文件并仅显示文本文件中的第二个路径,但没有文件夹的任何信息。以下是我的代码:
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);
}
}
}
我在考虑使用foreach将每行内容复制到变量中,或者将每行内容放入数组中并循环遍历以收集信息。
请问有人能够建议我哪种方法最适合,这样我就可以去MSDN学习,因为我更愿意学习而不是被给予代码。
谢谢!
