通用HtmlHelper從任何類型的列表創建HTML表

Question

我想創建一個HtmlHelper創建一個HTML表。我希望幫助程序能夠獲取任何類型的對象列表以及要顯示爲列的對象屬性列表。這樣的事情：

public static HtmlString Table(this HtmlHelper helper, List<T> data, List<string> headers) 
    { 
     //Tags 
     TagBuilder table = new TagBuilder("table"); 
     TagBuilder tr = new TagBuilder("tr"); 
     TagBuilder td = new TagBuilder("td"); 
     TagBuilder th = new TagBuilder("th"); 

     //Inner html of table 
     StringBuilder sb = new StringBuilder(); 

     //Add headers 
     foreach (var s in headers) 
     { 
      th.InnerHtml = s; 
      tr.InnerHtml += th.ToString(); 
     } 
     sb.Append(tr.ToString()); 

     //Add data 
     foreach (var d in data) 
     { 
      tr.InnerHtml = ""; 
      foreach (var h in headers) 
      { 
       td.InnerHtml = d.h.ToString(); 
       tr.InnerHtml += td.ToString(); 
      } 
      sb.Append(tr.ToString()); 
     } 

     table.InnerHtml = sb.ToString(); 
     return new HtmlString(table.ToString()); 
    } 

這段代碼當然不起作用，但我想知道是否有可能做出類似的東西？我怎麼可能會這樣做。

編輯：

我選擇了以下解決方案，當時的想法是，該表只應包含在標題列表中指定的元素，所以這就是我想出了：

public static HtmlString Table<T>(this HtmlHelper helper, List<T> data, List<string> headers) 
{ 
    //Tags 
    TagBuilder table = new TagBuilder("table"); 
    TagBuilder tr = new TagBuilder("tr"); 
    TagBuilder td = new TagBuilder("td"); 
    TagBuilder th = new TagBuilder("th"); 

    //Inner html of table 
    StringBuilder sb = new StringBuilder(); 

    //Add headers 
    foreach (var s in headers) 
    { 
     th.InnerHtml = s; 
     tr.InnerHtml += th.ToString(); 
    } 
    sb.Append(tr.ToString()); 

    //Add data 
    foreach (var d in data) 
    { 
     tr.InnerHtml = ""; 
     foreach (var h in headers) 
     { 
      td.InnerHtml = d.GetType().GetProperty(h).GetValue(d, null).ToString(); 
      tr.InnerHtml += td.ToString(); 
     } 
     sb.Append(tr.ToString()); 
    } 

    table.InnerHtml = sb.ToString(); 
    return new HtmlString(table.ToString()); 
}

public HtmlTable BuildTable<T>(List<T> Data) 
{ 
    HtmlTable ht = new HtmlTable(); 
    //Get the columns 
    HtmlTableRow htColumnsRow = new HtmlTableRow(); 
    typeof(T).GetProperties().Select(prop => 
             { 
              HtmlTableCell htCell = new HtmlTableCell(); 
              htCell.InnerText = prop.Name; 
              return htCell; 
             }).ToList().ForEach(cell => htColumnsRow.Cells.Add(cell)); 
    ht.Rows.Add(htColumnsRow); 
    //Get the remaining rows 
    Data.ForEach(delegate(T obj) 
    { 
    HtmlTableRow htRow = new HtmlTableRow(); 
    obj.GetType().GetProperties().ToList().ForEach(delegate(PropertyInfo prop) 
    { 
     HtmlTableCell htCell = new HtmlTableCell(); 
     htCell.InnerText = prop.GetValue(obj, null).ToString(); 
     htRow.Cells.Add(htCell); 
    }); 
    ht.Rows.Add(htRow); 
    }); 
    return ht; 
} 

試試看。您需要撥打BuildTable<YourType>(list)。
