将日期从 DataGridView 传输到 Crystal Reports VB.NET

Question

当我使用这些代码Dim inDate As String = CStr(dgr.Cells(0).Value.ToString("MM-dd-yyyy")) 。 该错误表明从字符串“MM-dd-yyyy”到类型 integer 的转换无效。 但是当我使用这些代码时Dim inDate As String = CStr(dgr.Cells(0).Value 。它显示来自 GridView 的日期但具有时间格式。我只想显示日期，而不是日期时间。要从中传输数据网格视图到水晶报表。我使用了 DataSet 和 DataTable。表中日期列的数据类型是字符串。这些是我的完整代码。

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        Dim report1 As New payslip
        Try
            Dim ds As New DataSet1
            Dim ms As New MemoryStream
            CompanyLogo_Picture.Image.Save(ms, CompanyLogo_Picture.Image.RawFormat)
            Dim byt() As Byte = ms.ToArray
            ds.DataTable1.Rows.Add(byt)
            For Each dgr As DataGridViewRow In DataGridView3.Rows
                Dim inDate As String = CStr(dgr.Cells(0).Value.ToString("MM-dd-yyyy"))
                Dim inTime As TimeSpan = dgr.Cells(1).Value
                Dim outDate As String = CStr(dgr.Cells(2).Value.ToString("MM-dd-yyyy"))
                Dim outTime As TimeSpan = dgr.Cells(3).Value
                ds.DataTable2.Rows.Add(inDate, inTime, outDate, outTime)
            Next
            report1.SetDataSource(ds)
            report1.SetParameterValue("employeeName", TextBox6.Text)
            report1.SetParameterValue("companyName", CompanyName_Label.Text)
            report1.SetParameterValue("companyAddress", CompanyAddress_Label.Text)
            report1.SetParameterValue("dateFrom", DateTimePicker1.Text)
            report1.SetParameterValue("dateTo", DateTimePicker2.Text)
            report1.SetParameterValue("dailyRate", payslip_dailyRate.Text)
            report1.SetParameterValue("totalDays", payslip_totalDays.Text)
            report1.SetParameterValue("mealAllowance", payslip_mealAllowance.Text)
            report1.SetParameterValue("transportationAllowance", payslip_transpoAllowance.Text)
            report1.SetParameterValue("medicalAllowance", payslip_medicalAllowance.Text)
            report1.SetParameterValue("grossPay", payslip_grossPay.Text)
            report1.SetParameterValue("SSS", payslip_sss.Text)
            report1.SetParameterValue("philHealth", payslip_philhealth.Text)
            report1.SetParameterValue("pagibig", payslip_pagibig.Text)
            report1.SetParameterValue("loans", payslip_loans.Text)
            report1.SetParameterValue("tardiness", payslip_tardiness.Text)
            report1.SetParameterValue("totalDeductions", payslip_totalDeductions.Text)
            report1.SetParameterValue("netPay", payslip_netPay.Text)
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
        Printer_Frm.CrystalReportViewer1.ReportSource = report1
        Printer_Frm.ShowDialog()
    End Sub

我尝试了所有我知道的代码来将这些数据转换为字符串类型，但没有任何效果。 还有其他方法可以获得我所需的 output 吗？ 谢谢^_^

我的问题现在解决了。 我使用这些代码Dim inDate As String = Format(dgr.Cells(0).Value, "MM-dd-yyyy")而不是这些Dim inDate As String = CStr(dgr.Cells(0).Value.ToString("MM-dd-yyyy")) 。 谢谢大家^_^
