在开发中有时要在后台获得某个View 或者 PartialView 生成的字符串，只要你熟悉Asp.Net MVC 生命周期就能理解和敲出下面的代码。没什么高深的，直接上代码：
1，输出View HTML 字符串：
/// <summary>
/// 描述：输出View HTML 字符串
/// </summary>
/// <param name="controller"></param>
/// <param name="viewName">视图文件名</param>
/// <param name="masterName">母板页文件名</param>
/// <returns></returns>
protected static string RenderViewToString(Controller controller, string viewName, string masterName)
{
IView view = ViewEngines.Engines.FindView(controller.ControllerContext, viewName, masterName).View;
using (StringWriter writer = new StringWriter())
{
ViewContext viewContext = new ViewContext(controller.ControllerContext, view, controller.ViewData, controller.TempData, writer);
viewContext.View.Render(viewContext, writer);
return writer.ToString();
}
}
2，输出PartialView HTML 字符串：
/// <summary>
/// 描述：输出PartialView HTML 字符串
/// </summary>
/// <param name="controller"></param>
/// <param name="partialViewName">部分视图文件名</param>
/// <returns></returns>
protected static string RenderPartialViewToString(Controller controller, string partialViewName)
{
IView view = ViewEngines.Engines.FindPartialView(controller.ControllerContext, partialViewName).View;
using (StringWriter writer = new StringWriter())
{
ViewContext viewContext = new ViewContext(controller.ControllerContext, view, controller.ViewData, controller.TempData, writer);
viewContext.View.Render(viewContext, writer);
return writer.ToString();
}
}
