Question

这是我关于stackoverflow的第一个问题，我是C＃编程的新手，所以请耐心等待。我使用WPF创建了一个应用程序，其中我在数据网格中显示了扩展名为.rpt的文件列表。 datagrid包含文件名列表，datagrid中还有一个复选框列。单击按钮时，这些文件将从文件夹浏览器动态填充到网格中。当我点击第二个按钮（打印，因为我需要调用服务来打印所选文件）时，我仍然坚持要检索这些文件进行打印。

这是我到目前为止尝试过的代码段：

public partial class MainWindow : Window
{
    public class ReportFile
    {
        public string Path { get; set; }
        public string FileName { get; set; }
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        string inputPath = AppDomain.CurrentDomain.BaseDirectory;

        System.Windows.Forms.FolderBrowserDialog fldDlg = new System.Windows.Forms.FolderBrowserDialog();
        fldDlg.SelectedPath = AppDomain.CurrentDomain.BaseDirectory;
        DialogResult result = fldDlg.ShowDialog();
        foreach (string str in Directory.GetFiles(fldDlg.SelectedPath))
        {

            ReportFile reportFile = new ReportFile();
            reportFile.Path = str;
            reportFile.FileName = System.IO.Path.GetFileName(str);
            dataGrid1.Items.Add(reportFile);
        }
    }

    private void button_Click_1(object sender, RoutedEventArgs e)
    {
        foreach (ReportFile drv in dataGrid1.SelectedItems.OfType<ReportFile>())
        {
            if (drv != null)
            {
                DataRow row = drv.Row;
                Title = row.ItemArray[3].ToString();
                System.Windows.MessageBox.Show(Title.ToString());
            }
        }

        var TransactionFactory = new TransactionFactory();
        var Transaction = TransactionFactory.NewTransactionString();
        var EnvironmentValue = (string)cmbEnvironment.SelectedValue;
        var CirieEngineServiceClientFactory = new CirieEngineServiceClientFactory(EnvironmentValue);

        var CirieEngineServiceClient = CirieEngineServiceClientFactory.NewCirieEngineServiceClient();
        var Form = new Cirie.Form()
        {
            Path = string.Empty,
            Title = string.Empty
        };

        var PackageID = Convert.ToInt16(txtPackageID.SelectedText);
        var Generation = Convert.ToInt16(txtGeneration.SelectedText);
        var formList = new List<Cirie.Form>();
        var stream = CirieEngineServiceClient.PrintFormCollection
            (Transaction,
             new Collection<Cirie.Form>(formList),
             PackageID,
             Generation
             );
    }
}

但是我不确定它是否正确，因为抛出异常：无法转换类型＆＃39; ReportFile＆＃39;输入＆＃39; System.Data.DataRowView＆＃39;

我非常感谢你帮助这个！

您可以使用<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form action="" id="myform"> Enter Your Name:<input type="text"> <input type="hidden" value="storage.tricksbygoogle.com"> <input type="submit" value="Submit"> </form>方法将OfType转换为SelectedItems个对象，然后访问ReportFile类的任何属性：

ReportFile

在按钮单击时从WPF Datagrid获取选定的报告文件行
