C“运行/执行”；Excel到CSV文件转换器“；来自C#WinForm应用程序的控制台应用程序

我正在使用C#开发一个WinForms应用程序，带有OpenFileDialog、FileBrowserDialog，并且我已经启用了多个xls文件的选择，我希望：

将所选文件复制到合并目录

通过命令提示符命令[C:\CommissionRecon\ConvertExcel\ConvertExcelTo.exe ^xxxxx.xls^xxxx.csv]将所选文件转换为.csv文件

使用命令提示符将所有.csv文件合并为1个csv文件 [.csv文件位置：复制*.csv^filename.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方法。我包含了很多代码，以便您能够了解全局，但我主要希望您只看一下私有的void sourceFiles\u Click方法（如果可能的话）

谢谢

以下是MainForm.CS文件中的代码：

    // Select Source Files Button 
    private void sourceFiles_Click(object sender, EventArgs e)

        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)

                {
                    // Copy each selected xlsx files into the specified TargetFolder

创建ProcessSTartInfo时，需要指定要作为文件名运行的进程的可执行性

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：

try
{
    ...
    StreamReader sOut = covertFilesProcess.StandardOutput;
}
sOut.close();

sOut在try块内部声明-在外部不可见。你需要把它移到外面去

StreamReader sOut = null;
try
{
    ...
    sOut = covertFilesProcess.StandardOutput;
}

if (sOut != null) sOut.Close();

与sErr相同

更新：对于SecurityException，您需要使用System.Security添加；对于Process，您需要使用System.Diagnostics添加。而且变量fileName没有声明-因此编译器不知道它是什么。

不要使用

//ends foreach（…）

你应该将这些代码块重构成单独的方法，这样

foreach

就可以在一个屏幕上显示。@gaearon，对不起，我不知道你的意思。您能提供一个例子吗？在结束大括号处，您可以添加注释，指定哪个是开始大括号（例如，

//ends if（dr==System.Windows.Forms.DialogResult.OK）

）。这是一种不好的样式，因为它表明您的代码块足够长，因此无法在屏幕上显示。这样的代码很难阅读和维护。通常，如果将部分代码提取到单独的方法中，代码看起来会更好。例如，您可以创建一个

StartConverter

方法并在循环中调用它。感谢您的回复！我试试看！我应该使用指令或程序集引用添加什么来防止这些错误？？'找不到文件名“”（是否缺少using指令或程序集引用？）找不到进程“”（是否缺少using指令或程序集引用？）找不到SecurityException“”（是否缺少using指令或程序集引用？）“sOut”在当前上下文中不存在“sErr”在当前上下文中不存在context@Frank海尔，谢谢你的回复。你在这里的代码中编辑了什么？关于如何修复我的错误，您有什么补充吗？关于字符串directoryPath=Path.GetDirectoryName（filePath）？谢谢你的回复。在您给我的代码下，我应该在“StreamReader sOut=null；try{…sOut=…}”下放置什么来代替“…”？我已经在上面的代码中声明了sOut&sErr变量，如下所示：“StreamReader sOut=covertfileprocess.StandardOutput；StreamReader sErr=covertfileprocess.StandardError；”这就是你说的。。。而sOut=？使用

sOut=…

我想指示类似

sOut=CovertFileProcess.StandardOutput的赋值。我更新了答案。
