VB.NET 2维数组排序排序和赋值问题
窗体上添加3个标签数组排序vb.net，1个按钮数组排序vb.net，在按钮数组排序vb.net的单击事件里写代码数组排序vb.net，如下数组排序vb.net：
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
VB.NET 控件数组拖动排序
因为控件按的比较紧密，需要同时判断数据列是否拖动在某个控件上，如果超过控件宽度的一半，则默认把当前拖动的控件放到该控件后面。否则，位置不动
VB.net 数组怎么按任意元素的顺序排序输出
数组排序vb.net你直接传一个数组进去数组排序vb.net，而且是一个结构体数组数组排序vb.net，array.sort怎么知道根据结构中数组排序vb.net的哪一个属性进行排序数组排序vb.net？放一个c#的代码你看看，VB和C#很相似的
class Program
{
static void Main(string[] args)
{
People[] p = new People[3]
{
new People{name="张三"},
new People{name="李四"},
new People{name="张二名"}
};
//重点传一个实现了IComparer接口的类进去，告诉Array.Sort怎么排序
Array.Sort(p, new PeopleCompare());
foreach (var item in p)
{
Console.WriteLine(item.name);
}
Console.ReadKey();
}
}
//People结构体，换成类一样的
public struct People
{
public string name { get; set; }
}
//实现了IComparer接口的类
public class PeopleCompare : IComparer
{
public int Compare(object x, object y)
{
People p1 = (People)x ;
People p2 = (People)y;
return p1.name.CompareTo(p2.name);
}
}
二维数组排序 vb.net
Dim i As Integer, j As Integer, X As Single, Y As Single, M As Single
i = L
j = R
'找出数组的中点
M = MyArray((L + R) / 2, 0)
While (i = j)
'找出比中点大的数
While (MyArray(i, 0) M And i R)
i = i + 1
Wend
'找出比中点小的数
While (M MyArray(j, 0) And j L)
j = j - 1
Wend
'互换这两个数
If (i = j) Then
X = MyArray(i, 0)
Y = MyArray(i, 1)
MyArray(i, 0) = MyArray(j, 0)
MyArray(i, 1) = MyArray(j, 1)
MyArray(j, 0) = X
MyArray(j, 1) = Y
i = i + 1
j = j - 1
End If
Wend
'未完成时递归调用
If (L j) Then Call QuickSort(MyArray(), L, j)
If (i R) Then Call QuickSort(MyArray(), i, R)
End Sub
