命名空间不能直接包含字段或方法等成员,并且T4运行时文本模板vb.net中未定义“ReportTemplate”

texttemplate t4 report vb.net html

Kan_IT · 技术社区 · 1 年前

我会使用T4运行时文本模板,这样我就可以将数据传递到html模板并简单地呈现报告。但我有一个错误,是不是我的代码出了问题。

谢谢

Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim rpt = New ReportTemplate()
        rpt.Session = New Dictionary(Of String, Object)()
        rpt.Session("Model") = New ReportModel With {
            .CustomerName = "TEST",
            .Date = DateTime.Now,
            .OrderItems = New List(Of OrderItem)() From {
                New OrderItem() With {
                    .Name = "Product 1",
                    .Price = 100,
                    .Count = 2
                },
                New OrderItem() With {
                    .Name = "Product 2",
                    .Price = 200,
                    .Count = 3
                },
                New OrderItem() With {
                    .Name = "Product 3",
                    .Price = 50,
                    .Count = 1
                }
            }
        }
        rpt.Initialize()
        Me.WebBrowser1.DocumentText = rpt.TransformText()
    End Sub
End Class

要投影的模型

Public Class ReportModel
    Public Property CustomerName() As String
    Public Property [Date]() As DateTime
    Public Property OrderItems() As List(Of OrderItem)
End Class
Public Class OrderItem
    Public Property Name() As String
    Public Property Price() As Integer
    Public Property Count() As Integer
End Class

将运行时文本模板(也称为预处理文本模板)添加到项目中,并将其命名为ReportTemplate.tt

        .container {width:400px; height:100%;}

    <#
     index += 1
     Next
   Dim total= Model.OrderItems.Sum(Function(x) x.Count * x.Price)
