部分視圖到字符串

Question

我想獲得由PartialView呈現的HTML代碼。例如

var partView = PartialView("myView", myModel); 
string content =??; 

我應該放什麼而不是問號？

Answer 1

public static string RenderPartialToString(string controlName, object viewData) 
    { 
     ViewPage viewPage = new ViewPage() { ViewContext = new ViewContext() }; 

     viewPage.ViewData = new ViewDataDictionary(viewData); 
     viewPage.Controls.Add(viewPage.LoadControl(controlName)); 

     StringBuilder sb = new StringBuilder(); 
     using (StringWriter sw = new StringWriter(sb)) 
     { 
      using (HtmlTextWriter tw = new HtmlTextWriter(sw)) 
      { 
       viewPage.RenderControl(tw); 
      } 
     } 

     return sb.ToString(); 
    } 
string content = RenderPartialToString("myView", myModel);
