Asp.Net中应用Aspose.Cells输出报表到Excel 及样式设置

2024-08-29 09:55:55 223人阅读

解决思路：

1、找个可用的Aspose.Cells（有钱还是买个正版吧，谁开发个东西也不容易）；

2、在.Net方案中引用此Cells；

3、写个函数ToExcel(传递一个DataTable)，可以另写个SetCellStyle的函数专门给各列设置样式。

4、在按钮的Click事件中调用此ToExcel()即可。

注：想更详细了解的到Aspose网站去，那里有很多在线文档，够你看的了。也可以下载个Demo程序研究。

部分代码贴在这里，代码还有需要改进的地方，暂时这么用着，给自己以后方便查找，再者给真正接触此控件的同志们抛个砖头：

ExportToExcel()的：

[csharp] view plain copy

/// <summary>
/// 利用Aspose.Cells对DataTable数据生成Excel文件
/// </summary>
/// <returns>是否成功</returns>
/// <param name="response">包含存储路径，直接用Response即可</param>
/// <param name="dt">数据体</param>
/// <param name="FileName">文件名</param>
/// <param name="SheetName">sheet名</param>
/// <param name="Title">表头</param>
/// <param name="ColTitle">列标题，字符串数组</param>
/// <param name="ColName">列名，字符串数组</param>
/// <param name="ColWidth">列宽，整数数组</param>
/// <param name="ColStyle">列样式，整数数组，1=居中文本、2=特殊字体Georgia、3=居左文本、4=整数(x)、5=2位小数(x,xxx.xx)、6=日期(yyyy-M-d不带时间)、7=百分数(0.123=12.3%)</param>
/// <param name="ColTitleRow">列标题的开始行号，有title的设为1即可</param>
/// <param name="err">返回的错误信息</param>
