本文介绍了将Quick BASIC转换为VB.Net - 随机访问文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 我试图将旧的Quick BASIC程序转换为VB.Net。似乎没有任何直接替换旧的文件语句。建立一个数据库似乎对我的简单需求矫枉过正。 如何在VB.Net中执行以下操作? OPENtest.datFOR RANDOM AS#1 LEN = 20 FIELD#1,10 AS $,10 AS b $ LSET a $ = One LSET b $ =Two PUT#1,1 GET#1,1 PRINT a $,b $ CLOSE#1 解决方案 , FilePut 和 FileGet 语句应该是上面大部分代码的直接替换。 Microsoft.VisualBasic.FileOpen(1,test.dat,OpenMode.Random,OpenAccess.ReadWrite,OpenSh are.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 =& A& ; B =& input.B) FileClose(1) I'm trying to convert an old Quick BASIC program to VB.Net. There doesn't appear to be any direct replacement for the old file statements. Building a database seems like overkill for my simple needs.How can I do the following in VB.Net?OPEN "test.dat" FOR RANDOM AS #1 LEN = 20FIELD #1, 10 AS a$, 10 AS b$LSET a$ = "One"LSET b$ = "Two"PUT #1, 1GET #1, 1PRINT a$, b$CLOSE #1 解决方案 The Microsoft.VisualBasic.FileOpen, FilePut, and FileGet statements should be pretty direct replacements for most of your code above. 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) 这篇关于将Quick BASIC转换为VB.Net - 随机访问文件的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
