vb.net排名次 vbnet random

vb.net datagridview控件 如何点击列头进行排序的时候 第一次点击为降序 求助各路大神DataGridView.Sort(this.dataGridViewTextBoxColumn1, ListSortDirection.Descending);降序
DataGridView.Sort(this.dataGridViewTextBoxColumn1, ListSortDirection.Ascending);升序
dataGridViewTextBoxColumn1是列名
VB.NET中DATAGRIDVIEW做排名(要序号)求助?。。?/h2>第一种方式:手动设置,设置列允许重新排列,这样在单击datagridview的列名时,就会自动排序
第二种方式:自动排序,想要按那列排序 , 就设置那列的SortMode的属性为:Programmatic
VB.NET数组的排序法?如果你是从vb6刚过渡上vb 。net,建议还是用冒泡排序法,容易理解 。
如果你正努力学习vb 。net的方法,推荐一个例子如下:
Imports System
Imports System.Collections
Public Class SamplesArray
Public Class myReverserClass
Implements IComparer
' Calls CaseInsensitiveComparer.Compare with the parameters reversed.
Function Compare(x As Object, y As Object) As Integer _
Implements IComparer.Compare
Return New CaseInsensitiveComparer().Compare(y, x)
End Function 'IComparer.Compare
End Class 'myReverserClass
Public Shared Sub Main()
' Creates and initializes a new Array and a new custom comparer.
Dim myArr As [String]() ={"The", "QUICK", "BROWN", "FOX", "jumps", "over", "the", "lazy", "dog"}
Dim myComparer = New myReverserClass()
' Displays the values of the Array.
Console.WriteLine("The Array initially contains the following values:")
PrintIndexAndValues(myArr)
' Sorts a section of the Array using the default comparer.
Array.Sort(myArr, 1, 3)
Console.WriteLine("After sorting a section of the Array using the default comparer:")
PrintIndexAndValues(myArr)
' Sorts a section of the Array using the reverse case-insensitive comparer.
Array.Sort(myArr, 1, 3, myComparer)
Console.WriteLine("After sorting a section of the Array using the reverse case-insensitive comparer:")
PrintIndexAndValues(myArr)
' Sorts the entire Array using the default comparer.
Array.Sort(myArr)
Console.WriteLine("After sorting the entire Array using the default comparer:")
PrintIndexAndValues(myArr)
' Sorts the entire Array using the reverse case-insensitive comparer.
Array.Sort(myArr, myComparer)
Console.WriteLine("After sorting the entire Array using the reverse case-insensitive comparer:")
PrintIndexAndValues(myArr)
End Sub 'Main
Public Shared Sub PrintIndexAndValues(myArr() As [String])
Dim i As Integer
For i = 0 To myArr.Length - 1
Console.WriteLine("[{0}] : {1}", i, myArr(i))
Next i
Console.WriteLine()
End Sub 'PrintIndexAndValues
End Class 'SamplesArray
'This code produces the following output.
'
'The Array initially contains the following values:
'[0] : The
'[1] : QUICK
'[2] : BROWN
'[3] : FOX
'[4] : jumps
'[5] : over
'[6] : the

'[8] : dog

VB.net 排序vb.net排名次你这个是冒泡排序么vb.net排名次?从大到小么?
For j = 0 To lstNetworkRisk.Items.Count - 1 应该改成
For j = i To lstNetworkRisk.Items.Count - 1
另外尽量不要用GOTO语句 。而且完全也可以不用这个GOTO 。
还有不知道你用的什么版本的.net 如果是3.5的完全可以直接用linq 。
