VBA 选择文件

Private Function SelectFile(ByVal strFilter As String) As String
    Dim FileName As Variant
     '打开文件对话框返回的文件名，是一个全路径文件名，其值也可能是False，因此类型为Variant
    Dim sFileName As String                         '从FileName中提取的文件名
    Dim sPathName As String                         '从FileName中提取的路径名
    Dim aFile As Variant                            '数组，提取文件名sFileName时使用
     '调用Windows打开文件对话框
    FileName = Application.GetOpenFilename(strFilter) ' "CSV 文件 (*.csv),*.csv"
   
    If FileName = False Then                       '如果按“取消”键
        SelectFile = ""
    Else
        aFile = Split(FileName, "")                '在全路径中，以“”为分隔符，分成数据
        sPathName = aFile(0)                        '取盘符
        For i = 1 To UBound(aFile) - 1              '循环合成路径名
            sPathName = sPathName & "" & aFile(i)
        Next
        SelectFile = sPathName & "" & aFile(UBound(aFile))
