如何将ViewDataDictionary或ModelStateDictionary注入到TagHelper中？

using Microsoft.AspNetCore.Mvc.Rendering;
using Microsoft.AspNetCore.Mvc.ViewFeatures;
using Microsoft.AspNetCore.Razor.TagHelpers;

[HtmlTargetElement("custom-tag")]
public class CustomTagHelper : TagHelper
{
    private readonly ViewDataDictionary _viewData;
    private readonly ModelStateDictionary _modelState;

    public CustomTagHelper([ViewContext]ViewDataDictionary viewData, [ViewContext]ModelStateDictionary modelState)
    {
        _viewData = viewData;
        _modelState = modelState;
    }

    public override void Process(TagHelperContext context, TagHelperOutput output)
    {
        // 使用_viewData和_modelState来获取和操作视图数据或模型状态
        // 例如：
        var value = _viewData["key"];
        var errors = _modelState["property"].Errors;

        // 修改标签输出内容
        output.Content.SetContent("Custom Tag Content");
    }
}
