Italic 构造函数

定义

命名空间:

System.Windows.Documents

程序集:

PresentationFramework.dll

初始化 Italic 类的新实例。

重载

Italic()	初始化 Italic 类的新实例。
Italic(Inline)	使用指定的 Inline 对象作为其初始内容初始化 Italic 类的新实例。
Italic(Inline, TextPointer)	使用指定的 Inline 对象作为其初始内容初始化 Italic 类的新实例，并使用指定新 Inline 元素的插入位置的 TextPointer。
Italic(TextPointer, TextPointer)	使用指定的 TextPointer 对象初始化 Italic 类的新实例，这些对象指示新 Italic 将包含的内容选择的开始和结尾。

Italic()

初始化 Italic 类的新实例。

public:
 Italic();

public Italic ();

Public Sub New ()

Italic(Inline)

使用指定的 Inline 对象作为其初始内容初始化 Italic 类的新实例。

public:
 Italic(System::Windows::Documents::Inline ^ childInline);

public Italic (System.Windows.Documents.Inline childInline);

new System.Windows.Documents.Italic : System.Windows.Documents.Inline -> System.Windows.Documents.Italic

Public Sub New (childInline As Inline)

参数

childInline

Inline

新 Italic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 Italic element.
Run runx = new Run("Text to make italic.");

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

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

' After this line executes, the new element "italx"
' contains the specified Inline element, "runx".
Dim italx1 As New Italic(runx1)

Italic(Inline, TextPointer)

使用指定的 Inline 对象作为其初始内容初始化 Italic 类的新实例，并使用指定新 Inline 元素的插入位置的 TextPointer。

public:
 Italic(System::Windows::Documents::Inline ^ childInline, System::Windows::Documents::TextPointer ^ insertionPosition);

public Italic (System.Windows.Documents.Inline childInline, System.Windows.Documents.TextPointer insertionPosition);

new System.Windows.Documents.Italic : System.Windows.Documents.Inline * System.Windows.Documents.TextPointer -> System.Windows.Documents.Italic

Public Sub New (childInline As Inline, insertionPosition As TextPointer)

参数

childInline

Inline

初始内容。 此参数可以 null，在这种情况下，不会插入任何 Inline。

insertionPosition

TextPointer

在其创建后插入 Italic 元素的插入位置。

示例

以下示例演示了此构造函数的用法。

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

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

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

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

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

' After this line executes, the new element "italx"
' contains the specified Inline element, "runx".  Also, "italx" 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 italx2 As New Italic(runx2, parx2.ContentStart)

Italic(TextPointer, TextPointer)

使用指定的 TextPointer 对象初始化 Italic 类的新实例，这些对象指示新 Italic 将包含的内容选择的开始和结尾。

public:
 Italic(System::Windows::Documents::TextPointer ^ start, System::Windows::Documents::TextPointer ^ end);

public Italic (System.Windows.Documents.TextPointer start, System.Windows.Documents.TextPointer end);

new System.Windows.Documents.Italic : System.Windows.Documents.TextPointer * System.Windows.Documents.TextPointer -> System.Windows.Documents.Italic

Public Sub New (start As TextPointer, end As TextPointer)

参数

start

TextPointer

新 Italic 将包含的内容选择的开头。

end

TextPointer

新 Italic 将包含的内容选择的末尾。

例外

ArgumentNullException

start 或 endnull。

ArgumentException

start 和 end 无法解析为一系列适合由 Italic 元素机箱的内容;例如，如果 start 和 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 italic.");
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 Italic.  In this case, the new Italic
// will enclose the second text run, "run2".
Italic italx = new Italic(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 italic.")
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 Italic.  In this case, the new Italic
' will enclose the second text run, "run2".
Dim italx3 As New Italic(run2.ContentStart, run2.ContentEnd)
