在.NET环境下将报表导出Excel和Word

在VB.NET同样可以将报表导出到Excel和Word进行输出，制作出专业水平的报表。具体操作如下：(注：首先需添加引用，选择COM-->选择Microsoft Word Object Library和Microsoft Excel Object Library组件)
Private Function CreaTable() As DataTable
Dim dt As New DataTable()
dt.Columns.Add("列1", GetType(String))
dt.Columns.Add("列2", GetType(Integer))
dt.Columns.Add("列3", GetType(String))
dt.Columns.Add("列4", GetType(String))
Dim row, row1 As DataRow
row = dt.NewRow()
row!列1 = "行1"
row!列2 = 1
row!列3 = "d"
row!列4 = "a"
dt.Rows.Add(row)
row1 = dt.NewRow()
row1!列1 = "行2"
row1!列2 = 12
row1!列3 = "b"
row1!列4 = "c"
dt.Rows.Add(row1)
Return dt
End Function
'2.将表中的内容导出到Excel
Dim xlApp As New Excel.Application()
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
Dim rowIndex As Integer = 1
Dim colIndex As Integer = 0
xlBook = xlApp.Workbooks().Add
xlSheet = xlBook.Worksheets("sheet1")
Dim Table As New DataTable()
Table = CreaTable()
'将所得到的表的列名,赋值给单元格
Dim Col As DataColumn
Dim Row As DataRow
For Each Col In Table.Columns
colIndex = colIndex + 1
xlApp.Cells(1, colIndex) = Col.ColumnName
Next
'得到的表所有行,赋值给单元格
For Each Row In Table.Rows
rowIndex = rowIndex + 1
colIndex = 0
For Each Col In Table.Columns
