[英]C# - Running / Executing “Excel to CSV File Converter” Console App from C# WinForm App
我正在使用帶有OpenFileDialog,FileBrowserDialog的C#開發WinForms應用程序,並且我已經啟用了我想要的多個xls文件的選擇:
執行此控制台應用程序的語法是什么?
請檢查下面的代碼並推薦一些修復程序。 我包含了很多代碼,以便您可以獲得全局,但我主要是希望您在可能的情況下查看私有void sourceFiles_Click方法。
謝謝!
這是MainForm.CS文件中的代碼:
// 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-

創建ProcessSTartInfo時,需要指定要作為文件名運行的進程的可執行文件!
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;
首先要做的事情:
try
{
...
StreamReader sOut = covertFilesProcess.StandardOutput;
}
sOut.close();
sOut在try塊中聲明 - 它在外面不可見。 你需要將它移到外面
StreamReader sOut = null;
try
{
...
sOut = covertFilesProcess.StandardOutput;
}
if (sOut != null) sOut.Close();
與sErr相同
更新 :對於SecurityException,您需要使用System.Security添加,而對於您需要使用System.Diagnostics添加的Process。 並且未聲明變量fileName - 因此編譯器不知道它是什么。
