Question

VB中的代码非常少，而且我一直都被卡住了。有人能告诉我这个C＃代码的VB等价吗？

... THX

<%= Html.DropDownList("WillAttend", new[] {
                                    new SelectListItem { Text = "Yes, I'll be there",
                                                         Value = bool.TrueString },
                                    new SelectListItem { Text = "No, I can't come",
                                                         Value = bool.FalseString }
                                    }, "Choose an option") %>

感谢电视让我指向了正确的方向......我在VB中使用数组构造类型进行了挣扎 - 它一直都在那里....

<% Using Html.BeginForm()%>
    <p>Your name: <%=Html.TextBox("Name")%></p>
    <p>Your email: <%=Html.TextBox("Email")%></p>
    <p>Your phone: <%=Html.TextBox("Phone")%></p>
    <p>
        Will you attend?
        <%=Html.DropDownList("WillAttend", New SelectListItem() { _
           New SelectListItem With {.Text = "Yes, I'll be there", .Value = Boolean.TrueString}, _
           New SelectListItem With {.Text = "No, I can't come", .Value = Boolean.FalseString} _
           }, "Choose an option")%>
    </p>
    <input  type="submit" value="Submit RSVP" /> 

<% End Using%>

Answer 2

SelectList的VB等价物应为：

Dim yesNo as SelectList = {
    New SelectListItem With { .Text = "Yes, I'll be there", .Value = Boolean.TrueString }, _
    New SelectListItem With { .Text = "No, I can't come", .Value = Boolean.FalseString } _
}

Answer 3

我正在编写Adam Freeman的PRO ASP.NET MVC 5中的教程，并遇到了同样的问题。

本书在c＃中，我想用VB编写它们。

这对我有用：

@Html.DropDownListFor(Function(GuestResponse) GuestResponse.WillAttend, New SelectListItem() { _
    New SelectListItem With {.Text = "Yes, I'll be there", .Value = Boolean.TrueString}, _
    New SelectListItem With {.Text = "No, I can't come", .Value = Boolean.FalseString} _
                                      },"Choose an option")

Answer 4

这与Gordon上面的答案相同，但是在Razor语法中，而不是ASPX语法，以防对某人有帮助。（这对我有帮助： - ）

@Using Html.BeginForm()
 @<text>
    <p>Your name: @Html.TextBoxFor(Function(m) m.Name)</p>
    <p>Your email: @Html.TextBoxFor(Function(m) m.Email)</p>
    <p>Your phone: @Html.TextBoxFor(Function(m) m.Phone)</p>
    <p>
        Will you attend?
        @Html.DropDownList("WillAttend", New SelectListItem() { _
                                            New SelectListItem With {.Text = "Yes, I'll be there", .Value = Boolean.TrueString}, _
                                            New SelectListItem With {.Text = "No, I can't come", .Value = Boolean.FalseString}}, _
                                            "Choose an option")
    </p>
    <input type="submit" value="Submit RSVP" />
</text>
End Using
