C# ASP.NET MVC HtmlHelper用法汇总

1. @Html.Raw() 方法输出带有html标签的字符串:

如: @Html.Raw("<div style=‘color:red‘>Hello World!</div>")

结果:Hello World!

2. @html.ActionLink生成一个<a href=".."></a>标记:

如:@Html.ActionLink(“linkText”、“actionName”、“controlName”,new { id = " 911" },new{ target="_blank"})

结果:<a href = "/controlName/actionName/911">linkText</a>

3. @Url.Action返回一个url

如:@Url.Action(“actionName”、“controlName”,new { id = " 911" })

结果:/controlName/actionName/911

4. @Html.Action加载局部页面，公共部分的代码例如：header/footer/menu/logout...

如：@Html.Action("actionName", "controlName")

用法类似@Html.RenderAction

5. @Html.RenderAction

如：@{ Html.RenderAction("_VSPartial", "CMController");}

_VSPartial内容：

@model ActiveTesting
<div>
    <div>
        <div>
            <ul>
                <li>
                    <div>
                        <a>Hello World!</a>
                    </div>
                </li>

                @if (Model != null)
                {
                    <li><a>Li Li</a></li>
                }
            </ul>
        </div>
    </div>
</div>

原理：根据Controller → Model → View的顺序进行执行，然后把结果进行返回

6. @Html.RenderPartial

将用户控件直接嵌入当前页面

如：@{ Html.RenderPartial("_PatientMRPartial");}

_PatientMRPartial内容：

<div>
    <div>
        <div>
            <h3 class="pull-left">Hello World!</h3>
        </div>
    </div>
    <div>
        <div>
            <div>
                <div>
                    <div>
                        Tom
                    </div>
                </div>
            </div>
        </div>
        <div class="row cpnmedication-content-line">
            <div>
                <div>
                    <div class="pull-left">
                        Jim
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
