vb.net變成 數組組合情況輸出問題

我們一直強調成都網站制作、成都做網站、外貿營銷網站建設對于企業的重要性,如果您也覺得重要,那么就需要我們慎重對待,選擇一個安全靠譜的網站建設公司,企業網站我們建議是要么不做，要么就做好,讓網站能真正成為企業發展過程中的有力推手。專業網絡公司不一定是大公司,創新互聯公司作為專業的網絡公司選擇我們就是放心。

額，沒注意VB，用C#寫的。。。

輸出了的，你新建一個C#控制臺程序，把這段貼進去，運行一下就知道了

先輸入一組字符串，然后輸入一個整數，就會把所有的組合輸出出來

我把這段轉成VB再發一次吧

Module Module1

Sub Main()

count = 0

Dim s As String() = Console.ReadLine().Split(" ")

Dim array(0 To s.Length - 1) As Integer

For i As Integer = 0 To s.Length - 1

array(i) = Convert.ToInt32(s(i))

Next

Dim m As Integer = Convert.ToInt32(Console.ReadLine())

Dim arraylist As New List(Of Integer)

arraylist.AddRange(array)

Print(arraylist, m, Nothing)

Console.WriteLine("共有" + count.ToString() + "個")

Console.ReadKey()

End Sub

Sub Print(ByRef array As List(Of Integer), ByVal m As Integer, ByRef output As List(Of Integer))

If output Is Nothing Then

output = New List(Of Integer)()

End If

If m = 0 Then

For i As Integer = 0 To output.Count - 1

Console.Write(output(i).ToString() + " ")

Next

Console.Write(vbCrLf)

count = count + 1

Return

Else

For i As Integer = 0 To array.Count - 1

Dim array2 As New List(Of Integer)

Dim output2 As New List(Of Integer)

output2.AddRange(output.ToArray())

output.Add(array(i))

array2.AddRange(array.ToArray())

For j As Integer = 0 To i

Dim number As Integer = array(j)

array2.Remove(number)

Next

Print(array2, m - 1, output)

output.Clear()

output.AddRange(output2.ToArray())

Next

End If

End Sub

Dim count As Integer = 0

End Module

vb.net輸出數組

1.你說的這個有點問題,是要只輸出一次,也可做,

2.但問題是如果你數組還有就看不到了!這個做法有點問題

1.解決方法:

循環前面加入一個變量 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

VB.net 數組怎么按任意元素的順序排序輸出

你直接傳一個數組進去，而且是一個結構體數組，array.sort怎么知道根據結構中的哪一個屬性進行排序？放一個c#的代碼你看看，VB和C#很相似的

class Program

{

static void Main(string[] args)

{

People[] p = new People[3]

{

new People{name="張三"},

new People{name="李四"},

new People{name="張二名"}

};

//重點傳一個實現了IComparer接口的類進去，告訴Array.Sort怎么排序

Array.Sort(p, new PeopleCompare());

foreach (var item in p)

{

Console.WriteLine(item.name);

}

Console.ReadKey();

}

}

//People結構體，換成類一樣的

public struct People

{

public string name { get; set; }

}

//實現了IComparer接口的類

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);

}

}

在VB.net中，如何使幾個數組變量按照列表示出來，并輸出到指定的EXCEL表格中！

先在: My Project 中引用 Microsoft Excel 11.0 Object Library（這個是Excel 2003，Excel 2007 是12.0）,之后在窗體代碼中加入相關內容就行了。以下是一個窗體的簡單實例

假設在C盤根文件夾中有：TEST.xls

Public Class 引用EXCEL窗體

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) = "數組:A"

For Index = 0 To UBound(A)

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

Next

excelapp.Cells(1, 2) = "數組:B"

For Index = 0 To UBound(B)

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

Next

excelapp.Visible = True

End Sub

End Class

運行結果：

數組:A 數組:B

A 1

B 22

CC 34

C 50

D 16

99

14
