在BtnNext_Click方法，它只是從文本文件閱讀，就像是一個不同的文本文件，而不是從已經被打開了一個同一個文本文件。它不會逐行進行。 我需要幫助閱讀不同方法
下面是代碼：
public void ScrubData()
{
string FileName1;
string FilePath1;
// Display an OpenFile Dialog box for user
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "txt Files|*.txt";
openFileDialog1.Title = "Select a txt File";
// Show the Dialog. If user clicked OK in the dialog
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
try
{
String strFileName = openFileDialog1.FileName;
String strFilePath = System.IO.Path.GetDirectoryName(strFileName);
String fileName = System.IO.Path.GetFileNameWithoutExtension(strFileName);
String strFileNameAndPathNew = strFilePath +
openFileDialog1.InitialDirectory + "\\" + fileName + "_scrubbed.txt";
// If scrubbed file exists, delete it first
if (System.IO.File.Exists(strFileNameAndPathNew))
{
System.IO.File.Delete(strFileNameAndPathNew);
} // End IF
if (System.IO.File.Exists(strFileName))
{
int lineCount = System.IO.File.ReadAllLines(strFileName).Length;
System.IO.StreamReader file = new System.IO.StreamReader(strFileName);
// Status label
LblStatus.Text = "File Loaded Successfully";
LblStatus.Visible = true;
string line;
while ((line = file.ReadLine()) != null)
{
const char DELIM = '|';
// MessageBox.Show(line);
string[] word = line.Split(DELIM);
Txt2NormAccNum.Text = word[3];
//string accScrubbed = ReplaceData(word[0],"SSN");
Txt3NormAmnt.Text = word[4];
Txt4NormFirstNam.Text = word[1];
Txt5NormLastNam.Text = word[2];
Txt6NormSS.Text = word[0];
Txt7NormItem.Text = word[5];
} // End WHILE
} // End IF
else
{
// Status label
LblStatus.Text = "File Load Failed!";
LblStatus.Visible = true;
} // End ELSE
// Text box one code:
FileName1 = openFileDialog1.FileName;
Txt1.Text = FileName1;
//
} // End TRY
catch (Exception e1)
{
if (e1.Source != null)
{
Console.WriteLine("IOException source: {0}", e1.Source);
throw;
} // End IF
} // End CATCH
} // End IF
} // End Scrub Method
我需要重複使用的變量，如在我的下一個方法「strFileName」。
我通過在文本文件中的每一行創建一個以前&下一個按鈕循環：
public void BtnNext_Click(object sender, EventArgs e)
{
StreamReader myReader2 = new StreamReader("colin.txt");
string line2 = "";
while (line2 != null)
{
line2 = myReader2.ReadLine();
if (line2 != null)
{
const char DELIM = '|';
// MessageBox.Show(line);
string[] word = line2.Split(DELIM);
Txt2NormAccNum.Text = word[3];
Txt3NormAmnt.Text = word[4];
Txt4NormFirstNam.Text = word[1];
Txt5NormLastNam.Text = word[2];
Txt6NormSS.Text = word[0];
Txt7NormItem.Text = word[5];
//Txt12ScrubSS.Text;
//Txt10ScrubFirstNam.Text;
//Txt11ScrubLastNam.Text;
//Txt8ScrubAcctNum.Text;
//Txt9ScrubAmt.Text;
//Txt13ScrubItem.Text;
}
}
myReader2.Close();
} // end method
如果你看到什麼即時消息說：該設計是：用戶打開文件，從文件中的文本的第一行顯示在窗體上，然後我有一個'上一個'和'下一個'按鈕，我想通過同一個文件中的文本行來循環。
@Tim是啊我想我知道你在說什麼在這裏看看這個：

我真的不知道問題是什麼，但是整個'XXX'/'XXX結尾'確實會降低您的代碼可讀性。 –
根據你發佈的內容，很難說出你有什麼問題（如果有的話）。什麼是預期的行爲與發生了什麼？你是什麼意思，它看起來像在閱讀，就像它是一個不同的文件？您需要使用類字段（或屬性）來存儲文件路徑，以便您可以在不同的方法中重用它。 – JNYRanger
