我在 SQL Server 數(shù)據(jù)庫的文本列中輸入了以下 JSon：{ "tag" : {  "string" : "<input type=\"text\" [attributes] />",  "attributes" : {   "name" : {    "required" : true,    "label" : "Field name",    "description" : "Use only letters and minus sign",    "expert" : false   },   "id" : {    "required" : false,    "label" : "Field identifier",    "description" : "Use only letters and minus sign",    "expert" : true   },   "class" : {    "required" : false,    "default" : "form-control",    "label" : "Field styles",    "description" : "These must exist in the stylesheet, leave blank if you don't know about them",    "expert" : true   },   "required" : {    "required" : false,    "allowed" : [     "required",     ""    ],    "label" : "Is the field required?",    "description" : "If the user must enter a value in this field, use the word required",    "expert" : true   },好的，所以基本上這個 JSon 包含輸入字段的描述及其所有可能的屬性。標(biāo)簽鍵里面的字符串鍵，是字段的基本結(jié)構(gòu)。在另一個表中，我基于該結(jié)構(gòu)創(chuàng)建了一個字段，它在 JSon 中有以下信息：{ "tag" : {  "name" : "username",  "id" : "username",  "class" : "form-control",  "placeholder" : "Enter your name" }}使用 C# 我想將字段呈現(xiàn)為表單：public string RenderField()    {        var data = JObject.Parse(this.Data); //Data is the field that contains the definition of the field        var structure = JObject.Parse(this.FieldTypes.Datos); // FieldTypes defines the structure of each possible field type        string tagHtml = structure["tag"]["string"].ToString(); // This is the basic form of a form field        foreach(JProperty key in data["tag"])        {            tagHtml = tagHtml.Replace("[attributes]", key.Name + "=\"" + key.Value + "\" [attributes]");        }        return WebUtility.HtmlDecode(tagHtml).Replace("[attributes]", "");    }基本上一切都按預(yù)期工作，但由于某種原因，該字段未顯示，但其 htmlentities 如下所示：&lt;input type=&quot;text&quot; name=&quot;username&quot; id=&quot;username&quot; class=&quot;form-control&quot; placeholder=&quot;Enter your name&quot;  /&gt;我不知道為什么它不解碼字符串。有任何想法嗎？
