CarlosAg.ExcelXmlWriter是一三方dll控件，可以到http://www.carlosag.net/Tools/ExcelXmlWriter/Default.aspx
下载。他使用起来非常简单。在C#中使用方法：
using
CarlosAg.ExcelXmlWriter;
class
TestApp {
static
void
Main(
string
[] args) {
Workbook book
=
new
Workbook();
Worksheet sheet
=
book.Worksheets.Add(
"
Sample
"
);
WorksheetRow row
=
sheet.Table.Rows.Add();
row.Cells.Add(
"
Hello World
"
);
book.Save(
@"
c: est.xls
"
);
}
}
这样就生成了一简单的Excel文件就生成在C盘了。它生成的是xml形式的Excel。
一个workbook就是一个在内存中的Excel文件。您只需要对workbook进行操作，即可按您想要的形式构建一内存中的Excel文件。调用workbook的save方法就可以在内存中的Excel文件写入硬盘或http下载流中去。Workbook中主要有Styles
集合用于添加Excel文档中的样式分格。Worksheets集合用于添加Excel文档的sheet对象。
CarlosAg.ExcelXmlWrite的具体用法请官方网站http://www.carlosag.net
或网络上查询。
在.net web应用程序开发过程，经常会遇到Excel的导出功能，过去一直用微软的office组件，配置起来麻烦，而且服务端需要安装Excel程序，对环境的改变也会影响功能的正常运行。还会经常出现一些莫名其妙的问题。有了CarlosAg.ExcelXmlWriter这些问题都不会出现了。不需要任何配置东西。由于大多数是对DataTable数据的导出功能。所以我把CarlosAg.ExcelXmlWriter进行了二次封装，对于Web程序中的Excel导出功能做到了完全简化。如果要导出一个DataTable对象dt的数据到Excel中，只需要传入dt即可。当然Excel的表头就是dt中的列名。也可以对dt的列名进行自定义甚至实现多表头导出功能。下面我们来详细研究：
封装工作需要三个类来完成：
ExcelBook,Excel
主处理类。
ExcelColumn
，
Excel
表头字段类用于处理自定义表头时使用。
ExcelColumnCollection
，
Excel
表头字段集合，用于添加
Excel
表头。
ExcelBook类:

有需要源代码或dll文件的请到我博客上下载:http://foxwoo.com/?p=46
我的免费电影网站二：http://www.91free.org
CarlosAg.ExcelXmlWriter是一三方dll控件，可以到http://www.carlosag.net/Tools/ExcelXmlWriter/Default.aspx
下载。他使用起来非常简单。在C#中使用方法：
using
CarlosAg.ExcelXmlWriter;
class
TestApp {
static
void
Main(
string
[] args) {
Workbook book
=
new
Workbook();
Worksheet sheet
=
book.Worksheets.Add(
"
Sample
"
);
WorksheetRow row
=
sheet.Table.Rows.Add();
row.Cells.Add(
"
Hello World
"
);
book.Save(
@"
c: est.xls
"
);
}
}
这样就生成了一简单的Excel文件就生成在C盘了。它生成的是xml形式的Excel。
一个workbook就是一个在内存中的Excel文件。您只需要对workbook进行操作，即可按您想要的形式构建一内存中的Excel文件。调用workbook的save方法就可以在内存中的Excel文件写入硬盘或http下载流中去。Workbook中主要有Styles
集合用于添加Excel文档中的样式分格。Worksheets集合用于添加Excel文档的sheet对象。
CarlosAg.ExcelXmlWrite的具体用法请官方网站http://www.carlosag.net
或网络上查询。
在.net web应用程序开发过程，经常会遇到Excel的导出功能，过去一直用微软的office组件，配置起来麻烦，而且服务端需要安装Excel程序，对环境的改变也会影响功能的正常运行。还会经常出现一些莫名其妙的问题。有了CarlosAg.ExcelXmlWriter这些问题都不会出现了。不需要任何配置东西。由于大多数是对DataTable数据的导出功能。所以我把CarlosAg.ExcelXmlWriter进行了二次封装，对于Web程序中的Excel导出功能做到了完全简化。如果要导出一个DataTable对象dt的数据到Excel中，只需要传入dt即可。当然Excel的表头就是dt中的列名。也可以对dt的列名进行自定义甚至实现多表头导出功能。下面我们来详细研究：
封装工作需要三个类来完成：
ExcelBook,Excel
主处理类。
ExcelColumn
，
Excel
表头字段类用于处理自定义表头时使用。
ExcelColumnCollection
，
Excel
表头字段集合，用于添加
Excel
表头。

使用方法:
直接导出DataTable dt的数据以dt的列名为表头名
ExcelBook eb
=
new
ExcelBook(dt,
"
标题
"
);
eb.IsAutoFitWidth
=
true
;
//
自定适用列宽
eb.Author
=
""
;
//
作者
eb.LastAuthor
=
""
;
//
最后作者
eb.Company
=
""
;
//
公司
eb.Version
=
""
;
//
版本
eb.WriteExcelToClient(
"
Excel文件名
"
);
//
下载Excel文件
//
eb.WriteExcelToClient();
//
以标题为下载文件名
自定义表头名称
ExcelBook eb
=
new
ExcelBook(dt,
"
标题
"
);
ExcelColumnCollection ec
=
new
ExcelColumnCollection();
eb.AddColumnNamesCollection(ec);
ec.Add(
new
ExcelColumn(
"
姓名
"
));
ec.Add(
new
ExcelColumn(
"
性别
"
));
ec.Add(
new
ExcelColumn(
"
学历
"
));
ec.Add(
new
ExcelColumn(
"
政治面貌
"
));
eb.IsAutoFitWidth
=
true
;
//
自定适用列宽
eb.WriteExcelToClient(
"
Excel文件名
"
);
//
下载Excel文件
//
eb.WriteExcelToClient();
//
以标题为下载文件名
自定义多表头
ExcelBook eb
=
new
ExcelBook(dt,
"
标题
"
);
ExcelColumnCollection ec
=
new
ExcelColumnCollection();
//
第一层表头
eb.AddColumnNamesCollection(ec);
ec.Add(
new
ExcelColumn(
"
基本信息
"
,
2
));
ec.Add(
new
ExcelColumn(
"
高级信息
"
,
2
));
ExcelColumnCollection ec2
=
new
ExcelColumnCollection();
//
第二层表头
eb.AddColumnNamesCollection(ec2);
ec2.Add(
new
ExcelColumn(
"
姓名
"
));
ec2.Add(
new
ExcelColumn(
"
性别
"
));
ec2.Add(
new
ExcelColumn(
"
学历
"
));
ec2.Add(
new

"
政治面貌
"
));
eb.IsAutoFitWidth
=
true
;
//
自定适用列宽
eb.WriteExcelToClient(
"
Excel文件名
"
);
//
下载Excel文件
以GridView的头为表
ExcelBook eb
=
new
ExcelBook(dt,
"
标题
"
);
eb.SetColumnNameFromGridViewHeadRow(gridView1.HeaderRow);
eb.IsAutoFitWidth
=
true
;
//
自定适用列宽
eb.WriteExcelToClient(
"
Excel文件名
"
);
//
下载Excel文件
