这行使用 Lambda 表达式的 C# 在 VB.Net 中会是什么？

string s = blockRenderer.Capture(() => RenderPartialExtensions.RenderPartial(h, userControl, viewData));

具有以下功能的东西 - 但我不知道到底是如何......

What would this line of C# using Lambda expression be in VB.Net?

string s = blockRenderer.Capture(() => RenderPartialExtensions.RenderPartial(h, userControl, viewData));

Something with function of - but I can't figure out exactly how...

它应该是这样的：

Dim s As String = blockRenderer.Capture(Function() RenderPartialExtensions.RenderPartial (h, userControl, viewData))

It should be something like this:

Dim s As String = blockRenderer.Capture(Function() RenderPartialExtensions.RenderPartial (h, userControl, viewData))

在线查看此C# 到 VB.NET 转换器。它并不总是让事情变得完美，但在我使用它的所有时候它都做得很好。

Dim s As String = blockRenderer.Capture(Function() RenderPartialExtensions.RenderPartial(h, userControl, viewData))

Check out this online C# to VB.NET converter. It doesn't always get things perfect, but it does a pretty good job all the times I've used it.

Dim s As String = blockRenderer.Capture(Function() RenderPartialExtensions.RenderPartial(h, userControl, viewData))

Dim s As String = _
    blockRenderer.Capture( _
        Function() RenderPartialExtensions.RenderPartial(h, userControl, viewData) _
     )

Dim s As String = _
    blockRenderer.Capture( _
        Function() RenderPartialExtensions.RenderPartial(h, userControl, viewData) _
     )

VB.NET 中的 Lambda 表达式需要有返回值，解决方案是包装方法。

Public Shared Function RenderPartialToString(ByVal userControl As String, ByVal viewData As Object, ByVal tempData As Object, ByVal controllerContext As ControllerContext) As String

        Dim h As New HtmlHelper(New ViewContext(controllerContext, New WebFormView("omg"), viewData, tempData), New ViewPage())
        Dim blockRenderer As New MvcContrib.UI.BlockRenderer(controllerContext.HttpContext)
        Dim s = blockRenderer.Capture(New Action(Function() renderPartialLambda(h, userControl, viewData)))

        Return s

End Function





Private Shared Function renderPartialLambda(ByVal html As HtmlHelper, ByVal userControl As String, ByVal viewData As Object)
                RenderPartialExtensions.RenderPartial(html, userControl, viewData)
                Return Nothing
End Function

Lambda Expressions in VB.NET need to have a return value, the solution is a wrapper method.

Public Shared Function RenderPartialToString(ByVal userControl As String, ByVal viewData As Object, ByVal tempData As Object, ByVal controllerContext As ControllerContext) As String

        Dim h As New HtmlHelper(New ViewContext(controllerContext, New WebFormView("omg"), viewData, tempData), New ViewPage())
        Dim blockRenderer As New MvcContrib.UI.BlockRenderer(controllerContext.HttpContext)
        Dim s = blockRenderer.Capture(New Action(Function() renderPartialLambda(h, userControl, viewData)))

        Return s

End Function





Private Shared Function renderPartialLambda(ByVal html As HtmlHelper, ByVal userControl As String, ByVal viewData As Object)
                RenderPartialExtensions.RenderPartial(html, userControl, viewData)
                Return Nothing
End Function
