My97date applying C # extension methods in MVC

The my97date used in the project, the other fields are bound with the @Html. Editorfor (model = model. field), but the calendar control is bound with <input/>, but it is not particularly good to write.

In order to also be able to bind attributes with @html, an extension method is used. The code is as follows:

 Public Static classMy97datepicker {Private Static stringDefaultFormat ="YYYY-MM-DD"; /// <summary>          ///to build a control with a specific name/// </summary>          /// <param name= "helper" >HtmlHelper Object</param>          /// <param name= "name" >Control Name</param>          /// <returns>HTML text</returns>           Public StaticMvchtmlstring Calendar ( ThisHtmlHelper Helper,stringname) {            returnCalendar (helper, name, DefaultFormat); }        /// <summary>          ///to build a control with a specific name/// </summary>          /// <param name= "helper" >HtmlHelper Object</param>          /// <param name= "name" >Control Name</param>          /// <param name= "format" >display Format</param>          /// <returns>HTML text</returns>           Public StaticMvchtmlstring Calendar ( ThisHtmlHelper Helper,stringNamestringformat) {            returnGeneratehtml (Name,NULL, format); }        /// <summary>          ///to build a control with a specific name and initial value/// </summary>          /// <param name= "helper" >HtmlHelper Object</param>          /// <param name= "name" >Control Name</param>          /// <param name= "Date" >date and time to display</param>          /// <returns>HTML text</returns>           Public StaticMvchtmlstring Calendar ( ThisHtmlHelper Helper,stringname, DateTime date) {            returnCalendar (helper, name, date, DefaultFormat); }        /// <summary>          ///to build a control with a specific name and initial value/// </summary>          /// <param name= "helper" >HtmlHelper Object</param>          /// <param name= "name" >Control Name</param>          /// <param name= "Date" >date and time to display</param>          /// <param name= "format" >display Format</param>          /// <returns>HTML text</returns>           Public StaticMvchtmlstring Calendar ( ThisHtmlHelper Helper,stringName, DateTime date,stringformat) {            returngeneratehtml (name, date, format); }        /// <summary>          ///building controls with lambda expressions/// </summary>          /// <param name= "helper" >HtmlHelper Object</param>          /// <param name= "expression" >A lambda expression that specifies the property to display and the object to which it belongs</param>          /// <returns>HTML text</returns>           Public StaticMvchtmlstring Calendarfor<tmodel, Tproperty> ( ThisHtmlhelper<tmodel> Helper, Expression<func<tmodel, tproperty>>expression) {            returncalendarfor (helper, expression, DefaultFormat); }        /// <summary>          ///building controls with lambda expressions/// </summary>          /// <param name= "helper" >HtmlHelper Object</param>          /// <param name= "expression" >A lambda expression that specifies the property to display and the object to which it belongs</param>          /// <param name= "format" >display Format</param>          /// <returns>HTML text</returns>           Public StaticMvchtmlstring Calendarfor<tmodel, Tproperty> ( ThisHtmlhelper<tmodel> Helper, Expression<func<tmodel, tproperty>> Expression,stringformat) {            stringName =expressionhelper.getexpressiontext (expression);            DateTime value; Objectdata = Modelmetadata.fromlambdaexpression<tmodel, tproperty>(expression, helper.)

As long as we refer to the namespace of this method, we can use @html.calendarfor and other methods happily. Of course also need to refer to My97date JS file.
