我对c#非常陌生，目前只是在玩一些东西。我试图在一个窗口中创建一个带有按钮或标签的网格。如何创建包含面板的动态网格

我已经尝试实现这个收到一个错误声明

"抛出异常:'System. 'InvalidOperationException"PresentationFramework.dll"。addchild线。我已经附上

*注意，这不是家庭作业，我只是玩玩来熟悉一下c#

        Grid grid1;
        public MainWindow()
        {
            InitializeComponent();
            int cellCount = 14;
            int numCols = 3;
            int numRows = (cellCount + 1) / numCols;
            grid1 = new Grid();
            this.AddChild(grid1);

            for (int i = 0; i < numCols; ++i)
                this.grid1.ColumnDefinitions.Add(new ColumnDefinition());
            for (int i = 0; i < numRows; ++i)
                this.grid1.RowDefinitions.Add(new RowDefinition());
            foreach (var g in this.grid1.RowDefinitions)
            {
                g.Height = new GridLength(100);
            }
            foreach (var g in grid1.ColumnDefinitions)
            {
                g.Width = new GridLength(100);
            }
            for (int i = 0; i < cellCount; ++i)
            {
                int idx = grid1.Children.Add(new Label());
                Label x = grid1.Children[idx] as Label;
                x.Content = "Cell " + i;
                x.SetValue(Grid.RowProperty, i / numCols);
                x.SetValue(Grid.ColumnProperty, i % numCols);
            }
        }
    }
}

创建带有面板的动态网格

从XAML中删除Grid部分

如果你的代码看起来像这样

<Window x:Class="NameSpace.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow"
        Height="350"
        Width="525">
    <Grid></Grid>
</Window>

它应该看起来像

<Window x:Class="NameSpace.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow"
        Height="350"
        Width="525">
</Window>
