重载

名称 说明
FlowDocument()

初始化类的新空实例 FlowDocument 。
FlowDocument(Block)

初始化类的新实例 FlowDocument ，添加指定 Block 元素作为初始内容。

FlowDocument()

初始化类的新空实例 FlowDocument 。

public:
 FlowDocument();
public FlowDocument();
Public Sub New ()

适用于

FlowDocument(Block)

初始化类的新实例 FlowDocument ，添加指定 Block 元素作为初始内容。

public:
 FlowDocument(System::Windows::Documents::Block ^ block);
public FlowDocument(System.Windows.Documents.Block block);
new System.Windows.Documents.FlowDocument : System.Windows.Documents.Block -> System.Windows.Documents.FlowDocument
Public Sub New (block As Block)

参数

block
Block

从抽象 Block 类派生的对象，要添加为初始内容。

例外

ArgumentNullException

block 是 null。

示例

以下示例演示如何使用此构造函数。 在这种情况下， FlowDocument 包含由嵌套在段落中的文本运行组成的流元素块结构。

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...")))

下面的示例以编程方式构造一个简单的 2 x 2 表，然后使用 FlowDocument 构造函数创建包含该表的新 FlowDocument 表。 尽管使用了更复杂的流元素块结构，但使用构造函数与前面的示例相同。

// 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)

注解

包括block、BlockUIContainer、List和ParagraphSection的有效输入类型Table。
