美好的一天。
我是编码新手，需要你的帮助。
我正在尝试创建一个可以实现的应用程序。
我成功浏览文件并显示 TextBox1 中的所有文件，但无法从 TextBox1 获取/选择文件进行转换。
我在寻找什么？
到目前为止我在不同论坛上尝试过的内容分享如下
using System;
using System.Collections.Generic;
//using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using Word = Microsoft.Office.Interop.Word;
using Excel = Microsoft.Office.Interop.Excel;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using Spire.Doc;
using Spire.Xls;
using Spire.Presentation;
using Microsoft.Office.Interop.Excel;
namespace T_Converter
{
public partial class Form1 : Form
{
private object workbook;
public object ExcelVersion { get; private set; }
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
BTNClear.Enabled = false;
BTNConvert.Enabled = false;
}
private void BTNBrowse_Click(object sender, EventArgs e)
{
var dialog = new OpenFileDialog();
dialog.InitialDirectory = @"\Desktop";
dialog.Title = "Browse old office files";
// dialog.Filter = "Office Files (*.xls)|*.xls";
dialog.DefaultExt = ".xls";
//OpenFileDialog dialog = new OpenFileDialog();
dialog.Multiselect = true;
var result = dialog.ShowDialog();
foreach (string file in dialog.FileNames)
{
textBox1.AppendText(Path.GetFileName(file) + Environment.NewLine);
}
BTNConvert.Enabled = true;
BTNClear.Enabled = true;
}
private void BTNClear_Click(object sender, EventArgs e)
{
textBox1.Clear();
BTNClear.Enabled = false;
BTNConvert.Enabled = false;
}
private void BTNClose_Click(object sender, EventArgs e)
{
this.Close();
}
private void BTNConvert_Click(object sender, EventArgs e)
{
}
}
//Create a Workbook instance
namespace ConvertXlsToXlsx
{
class Program
{
static void main(string[] args)
{
//Create a Workbook instance
Excel.Workbook workbook = new Excel.Workbook();
//Load an XLS file
Workbook.LoadFromFile(@"\Desktop\Test.xlsx");
//Convert the file to XLSX format
workbook.SaveToFile(@"C:\Users\Test\Desktop\test.xlsx", ExcelVersion.Version2016);
MessageBox.Show("OK");
}
}
}
}
以下代码解决了我的问题。这篇文章的回复也有帮助，但我们公司的专家找到了完整的解决方案。
private void BTNBrowse_Click(object sender, EventArgs e)
{
var dialog = new OpenFileDialog();
dialog.InitialDirectory = @"\Desktop";
dialog.Title = "Browse old office files";
dialog.Filter = "Excel Files (*.xls)|*.xls|Word Files(*.doc)|*.doc|PowerPoint Files(*.ppt)|*.ppt";
dialog.DefaultExt = ".xls";
dialog.Multiselect = true;
var result = dialog.ShowDialog();
foreach (string file in dialog.FileNames)
{
textBox1.AppendText(file + Environment.NewLine);
}
// Update textbox2 with the total number of selected files in a formatted way
int totalFiles = dialog.FileNames.Length;
textBox2.Text = $"{totalFiles:D3}";
BTNConvert.Enabled = true;
BTNClear.Enabled = true;
}
private void BTNClear_Click(object sender, EventArgs e)
{
textBox1.Clear();
BTNClear.Enabled = false;
BTNConvert.Enabled = false;
progressBar1.Value = 0;
textBox2.Text = "000";
}
private void BTNClose_Click(object sender, EventArgs e)
{
this.Close();
}
private void BTNConvert_Click(object sender, EventArgs e)
{
// ProgressBar

for (int i = 0; i < textBox1.Lines.Length; i++)
{
string filepath = textBox1.Lines[i].Replace("\r\n", string.Empty);
string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(filepath);
string outputFilePath = Path.Combine(outputFolder, fileNameWithoutExtension);
if (filepath.EndsWith(".xls"))
{

workbook.SaveAs(outputXlsxFilePath, Excel.XlFileFormat.xlOpenXMLWorkbook);
}
catch (Exception ex)

finally
{
if (workbook != null)
Marshal.ReleaseComObject(workbook);

Marshal.ReleaseComObject(pptApp);
}
}
}
}
MessageBox.Show("Conversion completed. \nYour converted files are saved in ''Converted Files'' folder created on your desktop.");
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
for (int j = 1; j <= 100; j++)
{
// Wait 50 milliseconds.
Thread.Sleep(50);
// Report progress.
backgroundWorker1.ReportProgress(j);
}
}
private void backgroundWorker1_ProgressChange(object sender, ProgressChangedEventArgs e)
{
// Change the value of the ProgressBar
progressBar1.Value = e.ProgressPercentage;
// Set the text.
this.Text = e.ProgressPercentage.ToString();
}
}
}
问题已解决。 谢谢大家的帮助和支持。
