# MkDir 语句

在数据媒体中创建新目录。

## 语法:

    MkDir Text As String

## 参数:

「Text」: 用于指定要创建目录的名称和路径的任意字符串表达式。您也可以使用 URL 表示法。

如果不能确定路径，则在当前目录下创建指定的目录。

## 错误代码:

5 无效的过程调用

76 未找到路径

## 示例:

    Sub ExampleFileIO

    ' 有关文件组织的函数示例

    Const sFile1 As String = "file://c|/autoexec.bat"

    Const sDir1 As String = "file://c|/Temp"

    Const sSubDir1 As String ="测试"

    Const sFile2 As String = "Copied.tmp"

    Const sFile3 As String = "Renamed.tmp"

    Dim sFile As String

        sFile = sDir1 + "/" + sSubDir1

        ChDir( sDir1 )

        If Dir(sSubDir1,16)="" Then ' 目录是否存在？

            MkDir sSubDir1

            MsgBox sFile,0,"创建目录"

        End If

        sFile = sFile + "/" + sFile2

        FileCopy sFile1 , sFile

        MsgBox fSysURL(CurDir()),0,"当前目录"

        MsgBox sFile & Chr(13) & FileDateTime( sFile ),0,"Creation time"

        MsgBox sFile & Chr(13)& FileLen( sFile ),0,"文件长度"

        MsgBox sFile & Chr(13)& GetAttr( sFile ),0,"文件属性"

        Name sFile As sDir1 + "/" + sSubDir1 + "/" + sFile3

        ' 在同一个目录中重命名

        sFile = sDir1 + "/" + sSubDir1 + "/" + sFile3

        SetAttr( sFile, 0 ) ' 删除所有属性

        MsgBox sFile & Chr(13) & GetAttr( sFile ),0,"新文件属性"

        Kill sFile

        RmDir sDir1 + "/" + sSubDir1

    End Sub

    ' 将系统路径转换为 URL

    Function fSysURL( fSysFp As String ) As String

    Dim iPos As String

        iPos = 1

        iPos = Instr(iPos,fSysFp, getPathSeparator())

        Do While iPos > 0

            Mid( fSysFp, iPos , 1,"/")

            iPos = Instr(iPos+1,fSysFp, getPathSeparator())

        Loop

        ' DOS 中的冒号

        iPos = Instr(1,fSysFp,":")

        If iPos > 0 Then Mid( fSysFp, iPos , 1,"|")

        fSysURL = "file://" & fSysFp

    End Function
