VB.NET中，比较四个数字的大小 代码
用不到2个命令按钮 1个就够
在按钮的过程中写如下代码
dim x as long , y as long ,z as long ,j as long ,n as long
dim k as integer
x = val(text1.text)
y = val(text2.text)
z = val(text3.text)
j = val(text4.text)
if x = then k = k+1
if y= then k = k+1
if z= then k = k+1
if j= then k = k+1
' 若输入的数有负数 则必须先在这里写下 n=-.....（）
do
if x 0 and n = x then
text5.text = text5.text " " x
k = k +1
end if
if y 0 and n = then
text5.text = text5.text " " y
k = k +1
end if
if z 0 and n = z then
text5.text = text5.text " " z
k = k +1
end if
if j 0 and n = j then
text5.text = text.text " " j
k = k +1
end if
if k = 4 then exit for
n=n+1
loop
这是VB的代码。。。。 不知道.net 适用不

Q1: vB.net语言编写N个数字数组排序可自定义数组长度的
Dim d() As Integer
Dim n As Integer
Dim i As Integer
Dim j As Integer
Dim T As Integer
n = Val(InputBox("请输入n，确定数组的元素个数"))
ReDim d(n)
'用随机函数生成正整数数组
Randomize
For i = 1 To n
d(i) = Int(Rnd * 100 + 1)
Next i
'输出
For i = 1 To n
Print d(i),
Next i
'从小到大排序
For i = 1 To n - 1
For j = i + 1 To n
If d(i) d(j) Then
T = d(i)
d(i) = d(j)
d(j) = T
End If
Next j
Next i
'输出
For i = 1 To n
Print d(i),
Next i
Q2: 求vb.net(vb2010)程序代码 产生30个50以内的随机正整数，将他们从大到小排序后输出
vb2010写的：
Private Sub Button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click
Dim str As String = ""
Dim a(30) As Integer
Dim temp As Integer
str = str "生成的30个随机数字是 " vbCrLf
For i = 1 To 30
a(i) = Int(Rnd() * 50 + 1)
str = str a(i) " "
If i Mod 10 = 0 Then
str = str vbCrLf
End If
Next
str = str vbCrLf
For i = 1 To 30
For j = 1 To 30 - i
If a(j) a(j + 1) Then
temp = a(j + 1)
a(j + 1) = a(j)
a(j) = temp
End If
Next j
Next i
str = str "排序后的数字是 " vbCrLf
For i = 1 To 30
str = str a(i) " "
If i Mod 10 = 0 Then
str = str vbCrLf
End If
Next
TextBox6.Text = str
End Sub
运行结果：
生成的30个随机数字是
36 27 29 15 16 39 1 39 41 36
3 21 44 40 19 49 44 3 48 19
27 39 3 30 24 15 32 33 14 14
排序后的数字是
49 48 44 44 41 40 39 39 39 36
36 33 32 30 29 27 27 24 21 19
19 16 15 15 14 14 3 3 3 1
Q3: VB.NET 2维数组排序排序和赋值问题
窗体上添加3个标签，1个按钮，在按钮的单击事件里写代码，如下：
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a(,) As Integer = {{5, 6}, {1, 3}, {8, 9}, {72, 1}, {63, 4}}
Dim Temp As Integer
Dim i As Integer
Dim j As Integer
Dim x As Integer
Dim y As Integer
'显示排序前的数据
Label1.Text = "排序前数据：" vbCrLf
For i = 0 To 4
Label1.Text = Label1.Text a(i, 0) " " a(i, 1) vbCrLf
Next
For i = 0 To 3
For j = i + 1 To 4
If a(i, 0) a(j, 0) Then
Temp = a(i, 0)
a(i, 0) = a(j, 0)
a(j, 0) = Temp
Temp = a(i, 1)
a(i, 1) = a(j, 1)
a(j, 1) = Temp
End If
Next
Next
'显示排序前的数据
Label2.Text = "排序后数据：" vbCrLf
For i = 0 To 4
Label2.Text = Label2.Text a(i, 0) " " a(i, 1) vbCrLf
Next
'把第3行元素赋予X,Y
x = a(2, 0)
y = a(2, 1)
'输出X,Y
Label3.Text = "X=" x vbCrLf "Y=" y
End Sub
Q4: 编写一个 VB.NET 程序,产生 100 个 100 以内的随机数，将他们从大到小排序后输出
Private Sub Command1_Click()
Dim a(1 To 100) As Integer
Dim i As Integer, j As Integer, k As Integer
For i = 1 To 100 '给数组a一百个元素赋值，并换每行十个数字输出来窗体上
a(i) = Int(Rnd * 101)
k = k + 1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
For i = 100 To 2 Step -1 '用冒泡排序法对数组进行排序
For j = 1 To i - 1
If a(j) a(j + 1) Then
t = a(j): a(j) = a(j + 1): a(j + 1) = t
End If
Next j
Next i
For i = 1 To 100 '输出排好序的数组
k = k + 1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
End Sub
Q5: vb.net的随机3个数字，然后排序一下
给你一个最简单的冒泡排序代码：
将三个数放到一个数组中。
a(0)=val(text1.text):a(1)=val(text2.text):a(2)=val(text3.text)
dim flag as Boolean,temp as Integer
for i = 0 to 2
flag = true
for j = 2 to 1
if a(j)a(j-1) then
temp = a(j-1)
a(j-1) = a(j)
a(j) = temp
flag = false
end if
next j
if flag then Exit For
next i
text4.text=a(0):text5.text=a(1):text6.text=a(2)
