Question

您好我需要能够生成带有文本的动态矩形。我现在遇到了问题，我无法在矩形上添加文字

我在这里生成矩形：

Sub FindFirstEmptyValue()

    Dim lastRow     As Long

    With Worksheets("Sheet1")
        lastRow = .Cells(.Rows.Count, 2).End(xlUp).Row + 1
        .Cells(lastRow, 2) = .Range("B3").value
        .Cells(lastRow, 3) = .Range("C3").value
    End With

End Sub

在研究其他类似问题时，答案总是避免使用矩形，但我希望继续使用矩形。

您可以将TextBlock子项添加到Grid，与Rectangle位于同一位置。

您还可以创建一个包含两个子节点的子网格，Rectangle和TextBlock，如下所示：

Grid subGrid = new Grid();
subGrid.Children.Add(rectangle);
TextBlock textblock = new TextBlock();
textblock.Text = "Text to add";
subGrid.Children.Add(textblock);

Kalender.Children.Add(grid);

或者将TextBlock添加为Border的子级，而不是使用Rectangle：

var border = new Border
{
    Background = termin.color,
    Child = new TextBlock { Text = "Some Text" }
};

Grid.SetRow(border, termin.start + 2);
Grid.SetColumn(border, termin.day * 2 - 1);
Grid.SetColumnSpan(border, 2);
Grid.SetRowSpan(border, termin.end - termin.start);
Kalender.Children.Add(border);

或使用适当对齐的标签：

var label = new Label
{
    Content = "Some Text",
    HorizontalContentAlignment = HorizontalAlignment.Center,
    VerticalContentAlignment = VerticalAlignment.Center,
    Background = termin.color
};

Grid.SetRow(label, termin.start + 2);
Grid.SetColumn(label, termin.day * 2 - 1);
Grid.SetColumnSpan(label, 2);
Grid.SetRowSpan(label, termin.end - termin.start);
Kalender.Children.Add(label);

是的，事实证明答案很简单而且我是个白痴。我这样解决了：

public  void ShowAppointements()
    {
        foreach (Termin termin in MainWindow.termine)
        {
            if (termin.week == Int32.Parse(txtWeek.Content.ToString()))
            {
                Rectangle rectangle = new Rectangle();
                TextBlock textblock = new TextBlock();
                Kalender.Children.Add(rectangle);
                Kalender.Children.Add(textblock);
                Grid.SetRow(rectangle, termin.start + 2);
                Grid.SetColumn(rectangle, termin.day * 2 - 1);
                Grid.SetColumnSpan(rectangle, 2);
                Grid.SetRowSpan(rectangle, termin.end - termin.start);
                Grid.SetRow(textblock, termin.start + 2);
                Grid.SetColumn(textblock, termin.day * 2 - 1);
                Grid.SetColumnSpan(textblock, 2);
                Grid.SetRowSpan(textblock, termin.end - termin.start);
                textblock.Text = termin.project + "\n" + termin.employee;
                rectangle.Fill = termin.color;

            }
        }
    }
