我正在尝试将旧的Quick BASIC程序转换为VB.Net.似乎没有任何直接替换旧文件语句.建立一个数据库对我的简单需求来说似乎有些过分.
如何在VB.Net中执行以下操作？
OPEN "test.dat" FOR RANDOM AS #1 LEN = 20 FIELD #1,10 AS a$,10 AS b$ LSET a$= "One" LSET b$= "Two" PUT #1,1 GET #1,1 PRINT a$,b$ CLOSE #1
解决方法
Microsoft.VisualBasic.FileOpen,FilePut和
FileGet语句应该是上述大多数代码的直接替代品.
Microsoft.VisualBasic.FileOpen(1,"test.dat",OpenMode.Random,OpenAccess.ReadWrite,OpenShare.Shared)
Dim output As New Fields
output.A = "One"
output.B = "Two"
Microsoft.VisualBasic.FilePut(1,output,1)
Dim input As New Fields
Microsoft.VisualBasic.FileGet(1,input,1)
Debug.WriteLine("A = " & input.A & "; B = " & input.B)
FileClose(1)
