我正在使用带有 OpenFileDialog、FileBrowserDialog 的 C# 开发一个 WinForms 应用程序,并且我已经启用了我想要的多个 xls 文件的选择:
[.csv 文件位置:复制 *.csv ^ 文件名.csv]
执行此控制台应用程序的正确语法是什么?
请检查下面的代码并推荐一些修复。我包含了很多代码,以便您了解全局,但我主要希望您尽可能只查看私有(private) void sourceFiles_Click 方法。
谢谢!
这是 MainForm.CS 文件中的代码:
// Select Source Files Button
private void sourceFiles_Click(object sender, EventArgs e)
{
Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
this.sourceFileOpenFileDialog.InitialDirectory = "i:\\CommissisionReconciliation\\Review\\";
this.sourceFileOpenFileDialog.Filter = "Excel Files (*.xls;*.xlsx;)|*.xls;*.xlsx;|All Files (*.*)|*.*";
this.sourceFileOpenFileDialog.FilterIndex = 2;
this.sourceFileOpenFileDialog.RestoreDirectory = true;
this.sourceFileOpenFileDialog.Multiselect = true;
this.sourceFileOpenFileDialog.Title = "Excel File Browser";
DialogResult dr = this.sourceFileOpenFileDialog.ShowDialog();
if (dr == System.Windows.Forms.DialogResult.OK)
{
string consolidatedFolder = targetFolderBrowserDialog.SelectedPath;
// Read the files
foreach (String file in sourceFileOpenFileDialog.FileNames)
{
try
{
// Copy each selected xlsx files into the specified TargetFolder
System.IO.File.Copy(fileName, consolidatedFolder + @"\" + System.IO.Path.GetFileName(fileName));
// Convert each selected XLSX File to CSV Using the command prompt
// [I:\CommissisionReconciliation\App\ConvertExcel\ConvertExcelTo.exe ^ .XLS file location ^ filename.csv]
// example: ConvertExcelTo.exe ^ I:\CommissisionReconciliation\ Review\_Consolidated\ALH\2011-350-00-600070-
// 03-09alh-AMLHS of Florida.xlsx ^ 2011-350-00-600070-03-09alh-AMLHS of Florida.csv

// substring function to take off the extension from sourceFileOpenFileDialog.FileName

最佳答案
创建 ProcessSTARTInfo 时,需要将要运行的进程的可执行文件指定为文件名!
例如:
Process covertFilesProcess = new Process();
covertFilesProcess.StartInfo.WorkingDirectory = "I:\\CommissisionReconciliation\\App\\ConvertExcel\\";
covertFilesProcess.StartInfo.FileName = "ConvertExcelTo.exe";
covertFilesProcess.StartInfo.Arguments = "^ " + targetFolderBrowserDialog.SelectedPath + "^" + sourceFileOpenFileDialog.FileName + ".csv";
covertFilesProcess.StartInfo.UseShellExecute = true;
covertFilesProcess.StartInfo.CreateNoWindow = true;
covertFilesProcess.StartInfo.RedirectStandardOutput = true;
covertFilesProcess.StartInfo.RedirectStandardError = true;
covertFilesProcess.Start();
StreamReader sOut = covertFilesProcess.StandardOutput;
StreamReader sErr = covertFilesProcess.StandardError;
