Underline(Inline)

初始化 Underline 类的新实例，将指定的 Inline 对象作为新 Underline的初始内容。

public:
 Underline(System::Windows::Documents::Inline ^ childInline);
public Underline(System.Windows.Documents.Inline childInline);
new System.Windows.Documents.Underline : System.Windows.Documents.Inline -> System.Windows.Documents.Underline
Public Sub New (childInline As Inline)

参数

childInline
Inline

一个 Inline 对象，指定新 Underline内容的初始内容。

示例

以下示例演示了此构造函数的用法。

// A child Inline element for the new Underline element.
Run runx = new Run("Text to make underlined.");

// After this line executes, the new element "underx"
// contains the specified Inline element, "runx".
Underline underx = new Underline(runx);

' A child Inline element for the new Underline element.
Dim runx1 As New Run("Text to make underlined.")

' After this line executes, the new element "underx"
' contains the specified Inline element, "runx".
Dim underx1 As New Underline(runx1)

适用于

Underline(Inline, TextPointer)

初始化 Underline 类的新实例，将指定的 Inline 对象作为新 Underline的初始内容，以及指定新 TextPointer 元素的插入位置的 Inline。

public:
 Underline(System::Windows::Documents::Inline ^ childInline, System::Windows::Documents::TextPointer ^ insertionPosition);
public Underline(System.Windows.Documents.Inline childInline, System.Windows.Documents.TextPointer insertionPosition);
new System.Windows.Documents.Underline : System.Windows.Documents.Inline * System.Windows.Documents.TextPointer -> System.Windows.Documents.Underline
Public Sub New (childInline As Inline, insertionPosition As TextPointer)

参数

childInline
Inline

一个 Inline 对象，指定新 Underline内容的初始内容。 此参数可以是 null，在这种情况下，不会 Inline 插入任何参数。

insertionPosition
TextPointer

一 TextPointer 个指定插入位置，在创建元素后插入 Underline 元素，或者 null 不进行自动插入。

示例

以下示例演示了此构造函数的用法。

// A child Inline element for the new Underline element.
Run runx = new Run("Text to make underlined.");

// An empty paragraph will serve as the container for the new Underline element.
Paragraph parx = new Paragraph();

// After this line executes, the new element "underx"
// contains the specified Inline element, "runx".  Also, "underx" is
// inserted at the point indicated by the insertionPosition parameter, 
// which in this case indicates the content start position in the Paragraph 
// element "parx".
Underline underx = new Underline(runx, parx.ContentStart);

' A child Inline element for the new Underline element.
Dim runx2 As New Run("Text to make underlined.")

' An empty paragraph will serve as the container for the new Underline element.
Dim parx2 As New Paragraph()

' After this line executes, the new element "underx"
' contains the specified Inline element, "runx".  Also, "underx" is
' inserted at the point indicated by the insertionPosition parameter, 
' which in this case indicates the content start position in the Paragraph 
' element "parx".
Dim underx2 As New Underline(runx2, parx2.ContentStart)

适用于

Underline(TextPointer, TextPointer)

初始化 Underline 类的新实例，采用两个 TextPointer 对象，这些对象指示新 Underline要包含的内容的开始和结尾。

public:
 Underline(System::Windows::Documents::TextPointer ^ start, System::Windows::Documents::TextPointer ^ end);
public Underline(System.Windows.Documents.TextPointer start, System.Windows.Documents.TextPointer end);
new System.Windows.Documents.Underline : System.Windows.Documents.TextPointer * System.Windows.Documents.TextPointer -> System.Windows.Documents.Underline
Public Sub New (start As TextPointer, end As TextPointer)

参数

start
TextPointer

一个 TextPointer 指示要由新 Underline内容包含的内容的开头。

end
TextPointer

一个 TextPointer 指示要由新 Underline内容包含的内容的末尾。

例外

ArgumentNullException

当或start为 end 时引发。

ArgumentException

当和start不解析为适合元素end机箱的一系列内容时Underline引发，例如，如果start并end指示不同段落中的位置。

示例

以下示例演示了此构造函数的用法。

// Create a paragraph and three text runs to serve as example content.  
Paragraph parx = new Paragraph();
Run run1 = new Run("Text run 1.");
Run run2 = new Run("Text run 2, make underlined.");
Run run3 = new Run("Text run 3.");

// Add the three text runs to the paragraph, separated by linebreaks.
parx.Inlines.Add(run1);
parx.Inlines.Add(new LineBreak());
parx.Inlines.Add(run2);
parx.Inlines.Add(new LineBreak());
parx.Inlines.Add(run3);

// After this line executes, the selection of content
// indicated by the "start" and "end" parameters will be
// enclosed by the new Underline.  In this case, the new Underline
// will enclose the second text run, "run2".
Underline underx = new Underline(run2.ContentStart, run2.ContentEnd);

' Create a paragraph and three text runs to serve as example content.  
Dim parx As New Paragraph()
Dim run1 As New Run("Text run 1.")
Dim run2 As New Run("Text run 2, make underlined.")
Dim run3 As New Run("Text run 3.")

' Add the three text runs to the paragraph, separated by linebreaks.
parx.Inlines.Add(run1)
parx.Inlines.Add(New LineBreak())
parx.Inlines.Add(run2)
parx.Inlines.Add(New LineBreak())
parx.Inlines.Add(run3)

' After this line executes, the selection of content
' indicated by the "start" and "end" parameters will be
' enclosed by the new Underline.  In this case, the new Underline
' will enclose the second text run, "run2".
Dim underx As New Underline(run2.ContentStart, run2.ContentEnd)

注解

此构造函数旨在初始化一个新 Underline 元素，使其包含一系列预先存在的内容。
