问题描述
Dim rp As New ReportDocument
Dim myData As New MyDataSet
Dim dt As New MyDataSet.UserDataTable
Dim FirstRow As MyDataSet.UserRow = _
CType(myData.User.NewRow, MyDataSet.UserRow)
FirstRow.MemberID = "1"
FirstRow.FirstName = "Amir Hossein"
FirstRow.LastName = "Rahnama"
myData.User.Rows.Add(FirstRow)
Dim SecondRow As MyDataSet.UserRow = _
CType(myData.User.NewRow, MyDataSet.UserRow)
SecondRow.MemberID = "2"
SecondRow.FirstName = "Aziz"
SecondRow.LastName = "Khodaie"
myData.User.Rows.Add(SecondRow)
rp.Load("C:Report.rpt")
rp.SetDataSource(myData)
CRV1.ReportSource = rp
设置数据源的时候报错:
When setting the datasource It comes up with an error:

为了让您知道,我通过 Crystal Reports 2008 独立 IDE 创建了该报表,而不是在 VS2010 IDE 中生成它,并且它通过水晶报表向导绑定到该数据集.
To let you know, I created that report by Crystal Reports 2008 Stand-alone IDE rather than generating it in VS2010 IDE and it is binded to that dataset dutring the crystal report wizard.
推荐答案
您需要做的是,您将按以下顺序将属性添加到启动元素:
What you need to do is that you will add an attribute to startup element in the following order:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
