範例

下列範例示範使用此建構函式。 在這種情況下，包含 FlowDocument 一個由段落中巢狀的文字執行組成的流程元素區塊結構。

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));

Dim flowDocSimple As New FlowDocument(New Paragraph(New Run("A bit of text content...")))

以下範例程式化地構造一個簡單的 2 x 2 表格，然後利用建 FlowDocument 構子建立 FlowDocument 包含該表格的新表格。 雖然使用較複雜的流元素區塊結構，但建構子的使用方式與前述範例相同。

// A paragraph with sample text will serve as table content.
Paragraph tableText = new Paragraph(new Run("A bit of text content..."));

Table sampleTable = new Table();

// Create and add a couple of columns.
sampleTable.Columns.Add(new TableColumn());
sampleTable.Columns.Add(new TableColumn());

// Create and add a row group and a couple of rows.
sampleTable.RowGroups.Add(new TableRowGroup());
sampleTable.RowGroups[0].Rows.Add(new TableRow());
sampleTable.RowGroups[0].Rows.Add(new TableRow());

// Create four cells initialized with the sample text paragraph.
sampleTable.RowGroups[0].Rows[0].Cells.Add(new TableCell(tableText));
sampleTable.RowGroups[0].Rows[0].Cells.Add(new TableCell(tableText));
sampleTable.RowGroups[0].Rows[1].Cells.Add(new TableCell(tableText));
sampleTable.RowGroups[0].Rows[1].Cells.Add(new TableCell(tableText));

// Finally, use the FlowDocument constructor to create a new FlowDocument containing 
// the table constructed above.
FlowDocument flowDoc = new FlowDocument(sampleTable);

    ' A paragraph with sample text will serve as table content.
    Dim tableText As New Paragraph(New Run("A bit of text content..."))

    Dim sampleTable As New Table()

    ' Create and add a couple of columns.
    sampleTable.Columns.Add(New TableColumn())
    sampleTable.Columns.Add(New TableColumn())

    ' Create and add a row group and a couple of rows.
    sampleTable.RowGroups.Add(New TableRowGroup())
    sampleTable.RowGroups(0).Rows.Add(New TableRow())
    sampleTable.RowGroups(0).Rows.Add(New TableRow())

    ' Create four cells initialized with the sample text paragraph.
    sampleTable.RowGroups(0).Rows(0).Cells.Add(New TableCell(tableText))
    sampleTable.RowGroups(0).Rows(0).Cells.Add(New TableCell(tableText))
    sampleTable.RowGroups(0).Rows(1).Cells.Add(New TableCell(tableText))
    sampleTable.RowGroups(0).Rows(1).Cells.Add(New TableCell(tableText))

    ' Finally, use the FlowDocument constructor to create a new FlowDocument containing 
    ' the table constructed above.
Dim flowDocTable As New FlowDocument(sampleTable)
