vb.net代碼生成器 vb·net

怎么用VB.NET生成含有宏代碼的Excel

先創(chuàng)建一個(gè)模板e(cuò)xcel文件，然后作為資源放在程序中，先釋放這個(gè)文件，然后操作這個(gè)文件。

vb.net隨機(jī)產(chǎn)生英文字母的代碼

1.隨機(jī)產(chǎn)生英文字母

Randomize() '功能：初始化隨機(jī)數(shù)發(fā)生器

Me.txt1.Text = Chr(Asc("a") + Int(Rnd() * 26))

'Rnd 函數(shù)返回小于 1 但大于或等于 0 的值。

'0 = Rnd() * 26 26 是含小數(shù)位的數(shù)

'Int(Rnd() * 26) 轉(zhuǎn)換為整型，就是0~25的隨機(jī)數(shù)

'Asc("a") 得到a的ASCii數(shù)值，是整數(shù)97（A是65）

'a~z的ASCii為97~122 ，即為a~z之間的字母為97加（0~25）

'Asc("a") + Int(Rnd() * 26)為97到122的隨機(jī)數(shù)

'Chr（）又可以起到轉(zhuǎn)換成字符的功能，Chr(97)表示a （a轉(zhuǎn)換成數(shù)值又是Asc("a")=97）

'Chr(Asc("a") + Int(Rnd() * 26))就是a~z的隨機(jī)數(shù)了

Randomize() '再次初始化隨機(jī)數(shù)發(fā)生器

Me.txt2.Text = Chr(Asc("A") + Int(Rnd() * 26)) '這里是A~Z的隨機(jī)數(shù)

'也可以換這種寫(xiě)法

Randomize()

Me.txt1.Text = Chr(Int((26 * Rnd()) + 97)) '這里是a~z的隨機(jī)數(shù)

'這是在你知道ASCII碼的情況之下（a~z為97~122，A~Z為65~90）

'Rnd()為0~0.9999999.....的隨機(jī)數(shù)

' 26 * Rnd()為0~25.9999...的隨機(jī)數(shù)

'Int((26 * Rnd())為0~25的隨機(jī)數(shù)

'Int((26 * Rnd()) + 97)為97~122的隨機(jī)數(shù)

'Chr(Int((26 * Rnd()) + 97))就是a~z的隨機(jī)數(shù)了

Randomize()

Me.txt2.Text = Chr(Int((26 * Rnd()) + 65)) '這里是A~Z的隨機(jī)數(shù)

'至于同時(shí)在一處隨機(jī)大寫(xiě)或小寫(xiě)，ASCII碼的數(shù)字又不挨在一起（65-90,97-122），比較麻煩。想寫(xiě)的話(huà)，你可以自己想一下怎么辦

2.數(shù)字怎樣轉(zhuǎn)換成ASCII碼所對(duì)應(yīng)的字母

Chr()函數(shù)將數(shù)字轉(zhuǎn)換成ASCII對(duì)應(yīng)的字母，Asc()函數(shù)將字母根據(jù)ASCII表轉(zhuǎn)換成數(shù)字

Chr(97)表示a （a轉(zhuǎn)換成數(shù)值又是Asc("a")=97）

3.加到數(shù)組，你可以放在一個(gè)for循環(huán)里

比如

Dim arylst1 As New ArrayList

Dim arr1() As String '數(shù)組

Dim str1 As String

For i As Integer = 1 To 15 '比如我想要15個(gè)隨機(jī)字母

Randomize()

str1 = Chr(Int((26 * Rnd()) + 65)) '這里是A~Z的隨機(jī)數(shù)

arylst1.Add(str1)

ReDim arr1(arylst1.Count - 1) '這里是為了比較動(dòng)態(tài)，可以只改變 i 的范圍來(lái)決定要多少個(gè)隨機(jī)字母

'當(dāng)然也可以寫(xiě)死，在前面直接定義為 arr1(14)，下次要改的時(shí)候就要改定義的地方和i的范圍，改兩個(gè)地方

arylst1.CopyTo(arr1)

'就把數(shù)值拷貝到數(shù)組里面了

vb.net源代碼如何生成exe格式

vb.net編譯出來(lái)的exe只有依賴(lài).net

framework才能運(yùn)行

但有一些第三方工具可以用來(lái)把exe用到的assembly和dll打包成一個(gè)exe文件，不過(guò)這樣的結(jié)果就是exe體積非常大

比如.netz工具，它的官方地址：

使用很簡(jiǎn)單，比如你的exe文件是a.exe，直接netz

a.exe就可以把a(bǔ)和它用到的.net代碼一起打包成一個(gè)exe
