通过文件结构直接生成xls文件

以下代码演示了 直接通过excel可以识别的文件结构生成xls文件的方法，这样就可以不引用麻烦的ole了。

using
System;

using
System.Collections.Generic;

using
System.Text;

namespace
ConsoleApplication16

{

class
Program

{

static

void
Main(
string
[] args)

{

//不通过OLE生成excel文件的方法

ExcelWriter excel =
new
ExcelWriter(@
"c:/test.xls"
);

excel.BeginWrite();

excel.WriteString(0, 0,
"Name"
);

excel.WriteString(0, 1,
"Score"
);

excel.WriteString(1, 0,
"jinjazz"
);

excel.WriteNumber(1, 1, 100);

excel.WriteString(2, 0,
"游客"
);

excel.WriteNumber(2, 1, 0);

excel.EndWrite();

}

}
