【TagHelper进阶系列】在TagHelper中使用其他TagHelper

var writer = new System.IO.StringWriter();
var basedataTagHelper = new TagHelper_SelectBasedata(Generator, modelMetadataProvider)
{
    //Url = Url.Action(baseData.Action, baseData.Controller),
    //remoteViewModel = baseData.ViewModel,
    //被调用TagHelper的配置参数

};
var basedataOutput = new TagHelperOutput("basedata", new TagHelperAttributeList(),(useCachedResult, encoder) => Task.Factory.StartNew<TagHelperContent>(() => new DefaultTagHelperContent()));
var basedataContext = new TagHelperContext(new TagHelperAttributeList(), new Dictionary<object, object>(), Guid.NewGuid().ToString());
basedataTagHelper.ProcessAsync(basedataContext, basedataOutput).GetAwaiter().GetResult();
basedataOutput.WriteTo(writer, HtmlEncoder.Default);

//添加到当前TagHelper的DOM中
 output.Content.AppendHtml(writer.ToString());
