建议用 DataGridView(你用的是它吧?)内建的排序方法来排序.介绍和示例代码可以参考MSDN:
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.
Console.WriteLine("After sorting a section of the Array using the default comparer:")
' Sorts a section of the Array using the reverse case-insensitive comparer.
Console.WriteLine("After sorting a section of the Array using the reverse case-insensitive comparer:")
' Sorts the entire Array using the default comparer.
Array.Sort(myArr)
Console.WriteLine("After sorting the entire Array using the default comparer:")
' 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:")
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
'After sorting a section of the Array using the default comparer:
' [1] : BROWN
'After sorting a section of the Array using the reverse case-insensitive comparer:
'After sorting the entire Array using the default comparer:
' [0] : BROWN
' [1] : dog
'After sorting the entire Array using the reverse case-insensitive comparer:
' [0] : the
' [1] : The
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
