Question

我正在尝试以下内容，我的报告中也没有参数，我也使用.Net Objects

 Dim data = GetDataConnection()
 Dim ds = (From th In data.TranHeads Where th.THCSCode = "YYY001"
              Select th).ToList

 Dim crySalesTran As ReportDocument = New IBS_DAL.rep_SalesTransaction

 crySalesTran.SetDataSource(ds.AsEnumerable)

 CrystalReportViewer1.ReportSource = crySalesTran

出于某种原因，当它达到setdatasource

时

TargetParameterCountException
参数计数不匹配。

Answer 1

我找到了答案虽然不确定为什么这样做而另一个选项却没有

Dim da = New System.Data.SqlClient.SqlDataAdapter("SELECT THSysRef, THCSCode FROM TranHead Where THCSCode = "YYY001" ", data.Connection)
Dim dtTH = New DataTable
da.Fill(dtTH)

Dim crySalesTran As ReportDocument = New IBS_DAL.rep_SalesTransaction
crySalesTran.Database.Tables(0).SetDataSource(dtTH)

CrystalReportViewer1.ReportSource = crySalesTran

参数计数不匹配。在setDataSource上
