WPF 批量讀取資料夾下TXT檔案寫入EXCEL
把翻到的很多以前寫的程式做個記錄，記錄學習過程，同時也方便以後查閱
https://github.com/Yiomo/ReadInfo
該APP會讀取選定資料夾下的TXT檔案並且直接將資訊按行寫入當前目錄下的excel表格PS.需要excel2010以上的元件&& NET4.0以上&&Microsoft.Office.Interop.Excel引用後需將嵌入互操作屬性設定為true
1.定義控制元件
<TextBlock x:Name="textBlock" HorizontalAlignment="Left" Height="51" Margin="29,10,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="27" Visibility="Hidden"/>
<Button x:Name="button" Content="OpenfileDLG" HorizontalAlignment="Left" Height="54" Margin="54,234,0,0" VerticalAlignment="Top" Width="114" Click="button_Click"/>
<Button x:Name="button1" Content="OpenfolderDLG" Margin="49,98,55,27" Click="button1_Click"/>
<ListBox x:Name="listBox" Height="60" Margin="61,10,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" Width="30" Visibility="Hidden"/>
<TextBlock x:Name="textBlock1" Margin="96,10,0,0" TextWrapping="Wrap" HorizontalAlignment="Left" Width="44" Height="60" VerticalAlignment="Top" Visibility="Hidden"/>
2.引用
using System.IO;using System.Windows;
using System.Windows.Input;
using System.Windows.Forms;
using Microsoft.Office.Interop.Excel;
3.開啟TXT檔案
private void button_Click(object sender, RoutedEventArgs e)
{
Microsoft.Win32.OpenFileDialog openfile = new Microsoft.Win32.OpenFileDialog();
openfile.DefaultExt = ".txt";
openfile.Filter = "Text documents (.txt)|*.txt";
bool? result = openfile.ShowDialog();
if (result == true)
{
textBlock.Text = openfile.FileName;
StreamReader readfile = new StreamReader(openfile .FileName);
textBlock.Text = readfile.ReadToEnd();
}
}
//////////該功能在APP裡面省略了，我也不知道為什麼當初放在APP裡面
4.遍歷資料夾下TXT檔案並寫入excel
private void button1_Click(object sender, RoutedEventArgs e)
{
FolderBrowserDialog openfolder = new FolderBrowserDialog();
DialogResult result = openfolder.ShowDialog();
if (result == System.Windows.Forms.DialogResult.Cancel)
{
return;
}
//textBlock.Text = openfolder.SelectedPath.Trim();
DirectoryInfo TheFolder = new DirectoryInfo(openfolder.SelectedPath);
foreach (FileInfo NextFile in TheFolder.GetFiles())
{
if (NextFile.Name .Contains(".txt")||NextFile.Name.Contains(".TXT"))
{
StreamReader readfile = new StreamReader(openfolder .SelectedPath+"\\"+NextFile.Name);
listBox.Items.Add(NextFile.Name);
}
}
int a = listBox.Items.Count;//統計多少檔案
Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.Application();
app.Visible = false;
app.UserControl = true;
Workbook workbook;
Worksheet worksheet;
workbook = app.Workbooks.Add(System.Reflection.Missing.Value);
worksheet = workbook.Worksheets.Add(System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value);
worksheet.Name = "test";
for (int i = 0; i < a; i++)//逐行寫入
{
//textBlock1.Text = "";
textBlock.Text = a.ToString();
string[] lines;
lines = File.ReadAllLines(openfolder.SelectedPath + "\\" + listBox.Items[i].ToString());
for (int j = 0; j < lines.Length; j++)
{
worksheet.Cells[i + 1, j + 1] = lines[j];
}
}
workbook.SaveAs(openfolder.SelectedPath+"\\"+"sum.xls", System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value);
workbook.Close(System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value);
System.Windows.MessageBox.Show("Done");
}
