清除DataGridView visual studio

Question

嗨我已经将cvs文件链接到我的帐户检查程序，但是当我按下重置按钮时需要数据视图清除，该按钮会重置电子邮件和密码字段，但我需要它来重置数据查看器，否则人员帐户信息保持不变屏幕可以有人帮忙吗？

Imports System.Text.RegularExpressions



Public Class Form1

Private Sub Label1_Click(sender As Object, e As EventArgs)

End Sub 

Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles     AddressBox1.TextChanged
        End Sub 





Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 
    Dim currentRow As String()

    Dim foundmatch As Boolean 

    Using parserDetails As New Microsoft.VisualBasic.FileIO.TextFieldParser("A453_datafile_4.csv") 
        parserDetails.SetDelimiters(",") 

        While Not parserDetails.EndOfData
            currentRow = parserDetails.ReadFields() 

            If AddressBox1.Text = currentRow(0) And TextBox2.Text = currentRow(1) Then
                Me.DataGridView1.Rows.Add(currentRow)
                foundmatch = True
            End If

        End While
    End Using

    If Not foundmatch Then
        MsgBox("The email or password you have enterd is incorrect", MsgBoxStyle.Critical, "Invalid Email")
    End If

End Sub
