ASP.NET MVC 将IList<T>导出Excel文档的泛型类(继承自ActionResult)

 

最近MVC项目中要使用到Excel导出功能,在网上找了些资料,自己写了一个通用的泛型类(ExcelResult)。因为是直接继承自ActionResult这个抽象类的,所以用起来很方便,在控制器的Action中直接实例化返回即可。本人的代码功底不是很好,写的代码有点烂,希望大伙指正。

 

废话少说,直接上类完整代码:

  View Code

  1 /// <summary>

  2     /// 提供将泛型集合数据导出Excel文档。

  3     /// </summary>

  4     /// <typeparam name="T"></typeparam>

  5     public class ExcelResult<T> : ActionResult where T : new()

  6     {

  7         public ExcelResult(IList<T> entity, string fileName)

  8         {

  9             this.Entity = entity;

 10             this.FileName = fileName;

 11         }

 12

 13         public ExcelResult(IList<T> entity)

 14         {

 15             this.Entity = entity;

 16

 17             DateTime time = DateTime.Now;

 18             this.FileName = string.Format("{0}_{1}_{2}_{3}",

 19                 time.Month, time.Day, time.Hour, time.Minute);

 20         }

 21

 22         public IList<T> Entity

 23         {

 24             get;

 25             set;

 26         }

 27

 28         public string FileName

 29         {

 30             get;

 31             set;

 32         }

 33

 34         public override void ExecuteResult(ControllerContext context)

 35         {

 36             if (Entity == null)

 37             {

 38                 new EmptyResult().ExecuteResult(context);

 39                 return;

 40             }

 41

 42             SetResponse(context);

 43         }

 44

 45         /// <summary>

 46         /// 设置并向客户端发送请求响应。

 47         /// </summary>

 48         /// <param name="context"></param>

 49         private void SetResponse(ControllerContext context)

 50         {

 51             StringBuilder sBuilder = ConvertEntity();

 52             byte[] bytestr = Encoding.Unicode.GetBytes(sBuilder.ToString());

 53

 54             context.HttpContext.Response.Clear();

 55             context.HttpContext.Response.ClearContent();

 56             context.HttpContext.Response.Buffer = true;

 57             context.HttpContext.Response.Charset = "GB2312";

 58             context.HttpContext.Response.ContentEncoding = System.Text.Encoding.UTF8;

 59             context.HttpContext.Response.ContentType = "application/ms-excel";

 60             context.HttpContext.Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ".xls");

 61             context.HttpContext.Response.AddHeader("Content-Length", bytestr.Length.ToString());

 62             context.HttpContext.Response.Write(sBuilder);

 63             context.HttpContext.Response.End();

 64         }

 65

 66         /// <summary>

 67         /// 把泛型集合转换成组合Excel表格的字符串。

 68         /// </summary>

 69         /// <returns></returns>

 70         private StringBuilder ConvertEntity()

 71         {

 72             StringBuilder sb = new StringBuilder();

 73

 74             AddTableHead(sb);

 75             AddTableBody(sb);

 76

 77             return sb;

 78         }

 79

 80         /// <summary>

 81         /// 根据IList泛型集合中的每项的属性值来组合Excel表格。

 82         /// </summary>

 83         /// <param name=&
