在.NET环境下将报表导出EXCEL和WORD

 在VB6开发环境下，本人使用EXCEL作过报表，在.NET环境下开发，本人使用水晶报表。但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 10.0 Object Library和Microsoft Excel 10.0 Object Library组件)

1．先创建一个DataTable，作为数据来源，也可以另将其它的数据源。

    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, colIndex As Integer

        rowIndex = 1

        colIndex = 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

                colIndex = colIndex + 1

                xlApp.Cells(rowIndex, colIndex) = Row(Col.ColumnName)

            Next

        Next

        With xlSheet

            .Range(.Cells(1, 1), .Cells(1, colIndex)).Font.Name = "黑体"

            '设标题为黑体字

            .Range(.Cells(1, 1), .Cells(1, colIndex)).Font.Bold = True

            '标题字体加粗

            .Range(.Cells(1, 1), .Cells(rowIndex, colIndex)).Borders.LineStyle = 1

            '设表格边框样式

        End With

        With xlSheet.PageSetup

            .LeftHeader = "" & Chr(10) & "&""楷体_GB2312,常规""&10公司名称："   ' & Gsmc

            .CenterHeader = "&""楷体_GB2312,常规""公司人员情况表&""宋体,常规""" & Chr(10) & "&""楷体_GB2312,常规""&10日 期："

            .RightHeader = "" & Chr(10) & "&""楷体_GB2312,常规""&10单位："

            .LeftFooter = "&""楷体_GB2312,常规""&10制表人："

            .CenterFooter = "&""楷体_GB2312,常规""&10制表日期："

            .RightFooter = "&""楷体_GB2312,常规""&10第&P页 共&N页"

        End With

        xlApp.Visible = True

3.将表中的内容导出到WORD

        Dim wordApp As New Word.Application()

        Dim myDoc As Word.Document

        Dim oTable As Word.Table

        Dim rowIndex, colIndex As Integer

        rowIndex = 1

        colIndex = 0

        wordApp.Documents.Add()

        myDoc = wordApp.ActiveDocument

        Dim Table As New DataTable()

        Table = CreaTable()

        oTable = myDoc.Tables.Add(Range:=myDoc.Range(Start:=0, End:=0), NumRows:=Table.Rows.Count + 1, NumColumns:=Table.Columns.Count)

        '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

            oTable.Cell(1, colIndex).Range.InsertAfter(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

                colIndex = colIndex + 1

                oTable.Cell(rowIndex, colIndex).Range.InsertAfter(Row(Col.ColumnName))

            Next

        Next

        oTable.Borders.InsideLineStyle = 1   

        oTable.Borders.OutsideLineStyle = 1

        wordApp.Visible = True
