1.隨機(jī)產(chǎn)生英文字母

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)

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)大寫或小寫,ASCII碼的數(shù)字又不挨在一起(65-90,97-122),比較麻煩。想寫的話,你可以自己想一下怎么辦
2.數(shù)字怎樣轉(zhuǎn)換成ASCII碼所對應(yīng)的字母
Chr()函數(shù)將數(shù)字轉(zhuǎn)換成ASCII對應(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)
Next
ReDim arr1(arylst1.Count - 1) '這里是為了比較動(dòng)態(tài),可以只改變 i 的范圍來決定要多少個(gè)隨機(jī)字母
'當(dāng)然也可以寫死,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編譯出來的exe只有依賴.net
framework才能運(yùn)行
但有一些第三方工具可以用來把exe用到的assembly和dll打包成一個(gè)exe文件,不過這樣的結(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
