Generating dynamic XML in Razor

问题:

I am using Razor outside of ASP.NET to generate XML documents from a template. I have the following code:

<event>
    <timeouts trigger='@Model.TriggerTimeout' />
    <parameters>
    @foreach (var parameter in Model.Parameters) {
        <@parameter.Key>@parameter.Value</@parameter.Key>
    }
    </parameters>
</event>

where Model.Parameters is just a name/value collection. My expected output should be:

<event>
    <timeouts trigger='100' />
    <parameters>
        <name1>value1</name1>
        <name2>value2</name2>
        <name3>value3</name3>
    </parameters>
</event>

but what I am actually getting is:

<event>
    <timeouts trigger='100' />
    <parameters>
        <name1>value1</@parameter.Key>
        <name2>value2</@parameter.Key>
        <name3>value3</@parameter.Key>
    </parameters>
</event>

What am I doing wrong? What is the secret sauce that I need to apply to make the dynamic elements close properly?

EDIT So now my model evolves to have multiple events, and my Razor code looks like this:

<events>
@foreach (var _event in Model.Events) {
    <@_event.Name enabled='@_event.Enabled'>
        <timeouts trigger='@_event.TriggerTimeout' />
        <parameters>
        @foreach (var parameter in _event.Parameters) {
            @:<@parameter.Key>@parameter.Value</@(parameter.Key)>
        }
        </parameters>
    </@_event.Name>
}
</events>

the output should be:

<events>
    <event1 enabled='true'>
        <timeouts trigger='100' />
        <parameters>
            <name1>value1</name1>
            <name2>value2</name2>
        </parameters>
    </event1>
    <event2 enabled='false'>
        <timeouts trigger='100' />
        <parameters>
            <name1>value1</name1>
        </parameters>
    </event2>
</events>

but it actually is:

<events>
    <event1 enabled='true'>
        <timeouts trigger='100' />
        <parameters>
            <name1>value1</name1>
            <name2>value2</name2>
        </parameters>
    </@_event.Name>
    <event2 enabled='false'>
        <timeouts trigger='100' />
        <parameters>
            <name1>value1</name1>
        </parameters>
    </@_event.Name>
</events>

SOLUTION Through a lot of trial and error, I eventually tracked down the missing secret sauce. The opening dynamic XML element needed a ?: prefix to render the closing element correctly. Most weird.

<events>
@foreach (var _event in Model.Events) {
    @:<@_event.Name enabled='@_event.Enabled'>
        <timeouts trigger='@_event.TriggerTimeout' />
        <parameters>
        @foreach (var parameter in _event.Parameters) {
            @:<@parameter.Key>@parameter.Value</@(parameter.Key)>
        }
        </parameters>
    </@_event.Name>
}
</events>

回答1:

You need to write </@(parameter.Key)> to stop Razor from thinking that that's an email address.
