Question

我使用的是Visual Basic，并且编程知识有限。我有一个文本框，包含四个txt或CSV文件的路径。我想将所有这些文件的数据导入DataGridView。我知道如何导入单个文件的数据，但不知道如何从多个文件导入数据。任何人都可以通过共享代码来帮助我。

注意：您需要将您的Datagridview标题文本与CSV文件中的标题匹配，以便在加载文件时更准确。

Private Sub Button1_Click（ByVal sender As System.Object，ByVal e As System.EventArgs）Handles Button1.Click

    OpenFileDialog1.InitialDirectory = "c:\temp\"
    OpenFileDialog1.Filter = "CSV files (*.csv)|*.CSV"
    OpenFileDialog1.FilterIndex = 2
    OpenFileDialog1.RestoreDirectory = True
    Me.OpenFileDialog1.Multiselect = True

    If (OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK) Then
        For x = 0 To OpenFileDialog1.FileNames.Count
            Try
                Dim fName As String = ""
                fName = OpenFileDialog1.FileNames(x)
                Me.TextBox1.Text += fName

                Dim TextLine As String = ""

                Dim SplitLine() As String

                If System.IO.File.Exists(fName) = True Then

                    Dim objReader As New System.IO.StreamReader(fName)

                    Do While objReader.Peek() <> -1

                        TextLine = objReader.ReadLine()

                        SplitLine = Split(TextLine, "|")

                        Me.DataGridView1.Rows.Add(SplitLine)

                    Loop

                Else

                    MsgBox("File Does Not Exist")

                End If
            Catch ex As Exception

            End Try
        Next
      MsgBox("Total files loaded = " & OpenFileDialog1.FileNames.Count)
    End If


End Sub
