font.Name = "Arial";
font.Underline = Underline.Dash;

builder.Write("Sample text.");
2.为Word插入一个段落
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

font.Size = 16;
font.Bold = true;
font.Color = System.Drawing.Color.Blue;
font.Name = "Arial";
font.Underline = Underline.Dash;

paragraphFormat.Alignment = ParagraphAlignment.Justify;
paragraphFormat.KeepTogether = true;

builder.Writeln("A whole paragraph.");
3.使用Aspose Word 为Word插入一个表格
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// 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.CellFormat.Orientation = TextOrientation.Downward;
builder.Writeln("This is row 2 cell 2");

builder.EndRow();

builder.EndTable();
