Asp.net MVC动态设置TextArea

Question

I'm working on an Asp.net MVC5 application.

I need to write some XML into a textarea, so it could be parsed by some JavaScript later in my project. As of now I have loaded the XML info into a ViewBag and was wondering how I could dynamically set a textarea with this information.

my controller (Index):

        XmlDocument doc = new XmlDocument();
        doc.Load("C:\\Tasks.xml");
        ViewBag.xml = doc.InnerXml();

Thanks, any help will be greatly appreciated.

Answer 1

-- html form

    @Html.TextArea("xml")
    <input type="submit" value="Save" />

-- html form

post action

[HttpPost]
public Actionresult SomeAction(string xml){...}

better solution (using strongly typed views)

model

public class XmlViewModel
{
    public string Xml { get; set; }
} 

controller

public Actionresult SomeAction()
{
    XmlDocument doc = new XmlDocument();
    doc.Load("C:\\Tasks.xml");
    var model = new XmlViewModel
    {
        Xml = doc.InnerXml();
    }

    return View(model);
}

[HttpPost]
public Actionresult SomeAction(XmlViewModel model)
{
    ...       

    return View(model);
}

view

@model XmlViewModel 

-- html form

    @Html.TextAreaFor(x => x.Xml)
    <input type="submit" value="Save" />

-- html form
