vb。net怎么输出数组 vb 遍历数组

VB.net 数组怎么按任意元素的顺序排序输出

你直接传一个数组进去,而且是一个结构体数组,array.sort怎么知道根据结构中的哪一个属性进行排序?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);

}

}

vb.net输出数组

1.你说的这个有点问题,是要只输出一次,也可做,

2.但问题是如果你数组还有就看不到了!这个做法有点问题

1.解决方法:

循环前面加入一个变量 dim Temp as Double=0

For i = 0 To 9

If score(i) avg and score(i)temp Then

TextBox3.Text = TextBox3.Text score(i) " "

if score(i)=avg then

temp=score(i)

end if

End If

Next

在VB.net中,如何使几个数组变量按照列表示出来,并输出到指定的EXCEL表格中!

先在: My Project 中引用 Microsoft Excel 11.0 Object Library(这个是Excel 2003,Excel 2007 是12.0),之后在窗体代码中加入相关内容就行了。以下是一个窗体的简单实例

假设在C盘根文件夹中有:TEST.xls

Public Class 引用EXCEL窗体

Private A() As String = {"A", "B", "CC", "C", "D"}

Private B() As Integer = {1, 22, 34, 50, 16, 99, 14}

Private excelapp As New Microsoft.Office.Interop.Excel.Application

Private excelworkbook As Microsoft.Office.Interop.Excel.Workbook

Private Sub 引用EXCEL_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim Index As Integer

excelworkbook = excelapp.Workbooks.Open("c:\test.xls")

excelapp.Application.Workbooks.Add(True)

excelapp.Cells(1, 1) = "数组:A"

For Index = 0 To UBound(A)

excelapp.Cells(Index + 2, 1) = A(Index)

Next

excelapp.Cells(1, 2) = "数组:B"

For Index = 0 To UBound(B)

excelapp.Cells(Index + 2, 2) = B(Index)

Next

excelapp.Visible = True

End Sub

End Class

运行结果:

数组:A 数组:B

A 1

B 22

CC 34

C 50

D 16

99

14
