Aspose.Words使用教程之插入文檔元素(一)

---

1.插入文本的字符串：

 插入文本的字符串需要通過DocumentBuilder.Write方法插入到文檔。文本格式是由字體屬性決定，這個對象包含不同的字體屬性(字體名稱,字體大小,顏色,等等)。

 一些重要的字體屬性也由[{ { DocumentBuilder } }]屬性允許您直接訪問它們。這些都是布爾屬性[{{Font.Bold}}],[{{Font.Italic}}], and [{{Font.Underline}}]。

注意字符格式設(shè)置將適用于所有插入的文本。

Example

使用DocumentBuilder插入格式化文本

c#

DocumentBuilder builder = new DocumentBuilder();
// Specify font formatting before adding text.
Aspose.Words.Font font = builder.Font;
font.Size = 16;
font.Bold = true;
font.Color = Color.Blue;
font.Name = "Arial";
font.Underline = Underline.Dash;
builder.Write("Sample text.");

Visual Basic

Dim builder As New DocumentBuilder()
' Specify font formatting before adding text.
Dim font As Aspose.Words.Font = builder.Font
font.Size = 16
font.Bold = True
font.Color = Color.Blue
font.Name = "Arial"
font.Underline = Underline.Dash
builder.Write("Sample text.")

 

2.插入一個段落

     DocumentBuilder.Writeln可以插入一段文本的字符串也能添加一個段落。當前字體格式也是由DocumentBuilder所規(guī)定。字體屬性和當前段落格式是由DocumentBuilder.ParagraphFormat屬性所決定。

Example

如何添加一個段落到文檔

C#

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Specify font formatting
Aspose.Words.Font font = builder.Font;
font.Size = 16;
font.Bold = true;
font.Color = System.Drawing.Color.Blue;
font.Name = "Arial";
font.Underline = Underline.Dash;
// Specify paragraph formatting
ParagraphFormat paragraphFormat = builder.ParagraphFormat;
paragraphFormat.FirstLineIndent = 8;
paragraphFormat.Alignment = ParagraphAlignment.Justify;
paragraphFormat.KeepTogether = true;
builder.Writeln("A whole paragraph.");

Visual Basic

Dim doc As New Document()
Dim builder As New DocumentBuilder(doc)
' Specify font formatting
Dim font As Aspose.Words.Font = builder.Font
font.Size = 16
font.Bold = True
font.Color = System.Drawing.Color.Blue
font.Name = "Arial"
font.Underline = Underline.Dash
' Specify paragraph formatting
Dim paragraphFormat As ParagraphFormat = builder.ParagraphFormat
paragraphFormat.FirstLineIndent = 8
paragraphFormat.Alignment = ParagraphAlignment.Justify
paragraphFormat.KeepTogether = True
builder.Writeln("A whole paragraph.")

3.插入一張表

使用DocumentBuilder創(chuàng)建一個表的基本算法是非常簡單的：

1.使用[{{DocumentBuilder.StartTable}}]啟動表；

2.使用[{{DocumentBuilder.InsertCell}}]插入單元格，這自動生成一個新行，如果需要，使用 [{{DocumentBuilder.CellFormat}}]屬性來指定單元格格式；

3.使用DocumentBuilder.methods寫入單元格內(nèi)容；

4.重復步驟2和3,直到行內(nèi)容寫完；

5.調(diào)用[{{DocumentBuilder.EndRow}}]來結(jié)束當前的行，如果需要，使用[{ { DocumentBuilder.RowFormat }}]屬性來指定行格式;

6.重復步驟2 - 5直到表完成;

7.調(diào)用[{{DocumentBuilder.EndTable}}]來完成表的創(chuàng)建。

Example

如何創(chuàng)建一個2行2列的格式化表格：

C#

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Table table = builder.StartTable();
// Insert a cell
builder.InsertCell();
// Use fixed column widths.
table.AutoFit(AutoFitBehavior.FixedColumnWidths);
builder.CellFormat.VerticalAlignment = CellVerticalAlignment.Center;
builder.Write("This is row 1 cell 1");
// Insert a cell
builder.InsertCell();
builder.Write("This is row 1 cell 2");
builder.EndRow();
// Insert a cell
builder.InsertCell();
// Apply new row formatting
builder.RowFormat.Height = 100;
builder.RowFormat.HeightRule = HeightRule.Exactly;
builder.CellFormat.Orientation = TextOrientation.Upward;
builder.Writeln("This is row 2 cell 1");
// Insert a cell
builder.InsertCell();
builder.CellFormat.Orientation = TextOrientation.Downward;
builder.Writeln("This is row 2 cell 2");
builder.EndRow();
builder.EndTable();

Visual Basic

Dim doc As New Document()
Dim builder As New DocumentBuilder(doc)
Dim table As Table = builder.StartTable()
' Insert a cell
builder.InsertCell()
' Use fixed column widths.
table.AutoFit(AutoFitBehavior.FixedColumnWidths)
builder.CellFormat.VerticalAlignment = CellVerticalAlignment.Center
builder.Write("This is row 1 cell 1")
' Insert a cell
builder.InsertCell()
builder.Write("This is row 1 cell 2")
builder.EndRow()
' Insert a cell
builder.InsertCell()
' Apply new row formatting
builder.RowFormat.Height = 100
builder.RowFormat.HeightRule = HeightRule.Exactly
builder.CellFormat.Orientation = TextOrientation.Upward
builder.Writeln("This is row 2 cell 1")
' Insert a cell
builder.InsertCell()
builder.CellFormat.Orientation = TextOrientation.Downward
builder.Writeln("This is row 2 cell 2")
builder.EndRow()
builder.EndTable()
