C# 将字符串值从列表传递到datagrid

我正在尝试编写一个方法，该方法通过Load按钮从文件系统中的某个位置获取xml.config文件，对其进行解析，然后处理元素属性type和mapTo中的特定字符串，从这些属性中获取一些子字符串。问题是，我得到的不是表中的字符串，而是一些行。有人知道问题出在哪里吗

按钮和方法调用如下所示：

private void button1_Click(object sender, RoutedEventArgs e)
        {
            OpenFileDialog fDialog = new OpenFileDialog();

            fDialog.Title = "Open XML file";
            fDialog.Filter = "XML files|*.config";
            fDialog.InitialDirectory = @"C:\";

            bool? control = fDialog.ShowDialog();
            if (control.Value)
            {
                var filePath = fDialog.FileName;
                ReadAdvancedConfigFile(filePath);
            }

        }

private void ReadAdvancedConfigFile(string path)
{
    XElement root = null;
    root = XElement.Load(new XmlTextReader(path));

    if (root != null)
    {
        XNamespace ns = "http://schemas.microsoft.com/practices/2010/unity";
        var registers = root.Element(ns + "unity").Element(ns + "container").Descendants(ns + "register");

        if (registers.Count() > 0)
            {
            var tipList = registers.Select(x => x.Attribute("type").Value);
            var mapToList = registers.Select(x => x.Attribute("mapTo").Value);
            List<string> listresult = new List<string>();
            List<string> listresultm = new List<string>();

                foreach (string tpl in tipList)
                {
                    int end = tpl.IndexOf(',');
                    int start = tpl.LastIndexOf('.', (end == -1 ? tpl.Length - 1 : end)) + 1;
                    string result = tpl.Substring(start, (end == -1 ? tpl.Length : end) - start);
                    listresult.Add(result);
                }
                foreach (string mpl in mapToList)
                {
                    int endm = mpl.IndexOf(',');
                    int startm = mpl.LastIndexOf('.', (endm == -1 ? mpl.Length - 1 : endm)) + 1;
                    string resultm = mpl.Substring(startm, (endm == -1 ? mpl.Length : endm) - startm);
                    listresultm.Add(resultm);
                }

                int maxLenList = Math.Max(listresult.Count, listresultm.Count);
                for (int i = 0; i < maxLenList; i++)
                {
                    if (i < listresult.Count && i < listresultm.Count)
                    {
                        _obsCollection.Add(new Tuple<string, string>(listresult[i], listresultm[i]));
                    }
                    else if (i >= listresult.Count)
                    {
                        _obsCollection.Add(new Tuple<string, string>(string.Empty, listresultm[i]));
                    }
                    else if (i >= listresultm.Count)
                    {
                        _obsCollection.Add(new Tuple<string, string>(listresultm[i], string.Empty));
                    }
                }
            tabela.ItemsSource = _obsCollection;

方法，该方法从xml文件获取值，为每个属性类型和mapTo获取子字符串，将它们放入两个单独的列表中，并尝试将列表内容写入datagrid，如下所示：

这就是我为字符串对创建元组的方法。在这个类中还有ReadAdvancedConfigFile方法和Load按钮的定义，当然：

    public partial class CreateAreaDialogWindow : System.Windows.Window
        {
            ObservableCollection<Tuple<string, string>> _obsCollection = new ObservableCollection<Tuple<string, string>>();

            public CreateAreaDialogWindow()
            {
                InitializeComponent();
            }
}

公共部分类CreateAreaDialogWindow:System.Windows.Window
{
ObservableCollection_obsCollection=新的ObservableCollection（）；
公共CreateAreaDialogWindow（）
{
初始化组件（）；
}
}

datagrid的XAML代码如下：

<DataGrid AutoGenerateColumns="False" Height="146" HorizontalAlignment="Left" Margin="34,275,0,0" Name="tabela" VerticalAlignment="Top" Width="384" SelectionChanged="tabela_SelectionChanged" />

---

希望我没有把事情弄得太复杂

您设置了

AutoGenerateColumns=“False”

，但未提供任何列

试试这个，它会起作用：

<DataGrid AutoGenerateColumns="True" />

---

或者查看如何创建列。

您可以添加问题的屏幕截图吗。“我还不太清楚。”帕特里克霍夫曼用线条截图的datagrid？或者别的什么？是的，这就是我的意思。@PatrickHofman因为某种原因不会发送照片。。。我会继续尝试。但它基本上是一个窗口，只有一个加载按钮，下面是DataGrid。在DataGrid中，我在两列中有行而不是字符串。我认为这一行可能有问题：tabela.ItemsSource=\u obscolection；因为我不确定ItemsSource能不能像那样工作？我知道了。我自己也看到了这个问题，但用一张图片更容易看出。别再担心了。看我的答案。我爱你，伙计！：D成功了！：）谢谢。我知道这很愚蠢，但我仍在学习，这可能很难：）谢谢你的链接。我需要它：）因为接下来我必须研究如何为每个值在该选项卡中添加复选框：）
