Text="我的VB.NET程序"

PuctureBox1.Image=Image.FromFile(图片路径如e:\pic.jpg)

End Sub

窗体Click事件：

Private Sub Form1_Click() Handles Me.Click

Text="单击窗体"

Label1.Text="欢迎使用VB.NET"

End Sub

vb.net求帮助 要用redim语句

写的比较粗糙，参考一下吧

Sub Main()

Dim numArr() As Double

Dim count As Integer = 1

Dim num As Double

Dim sumNum As Double = 0

Dim aveNum As Double

Dim flag As Integer = 0

While (True)

Console.Write("请输入第{0}个数:", count）

ReDim Preserve numArr(count - 1)

num = Convert.ToDouble(Console.ReadLine())

If num = 0 Then

Exit While

End If

numArr(count - 1) = num

count += 1

End While

If count 1 Then

Dim cha As Double

Dim minCha As Double = Double.MaxValue

For i As Integer = 0 To count - 1

sumNum += numArr(i)

Next

aveNum = sumNum / (count - 1)

For i As Integer = 0 To count - 1

cha = Math.Abs(aveNum - numArr(i))

If minCha = cha Then

minCha = cha

flag = i + 1

End If

Next

End If

Console.WriteLine("总共输入{0}个正数，平均值为{1}", count - 1, aveNum）

Console.WriteLine("最接近平均值的是第{0}个正数，值为{1}", flag, numArr(flag - 1)）

Console.ReadKey()

End Sub
