请教 自定义函数有时候会出现这个错误

 

 

此主题相关图片如下：fffff.jpg

代码发出来看看, 你是不是引用定义了,超出参数个数的参数了.   比如只有2个 你引用到第三个去了

代码问题，例如数组a长度是5，a(5)就会出错，因为5表示第六个元素

内部函数 取日期的  

 

Dim TimeServers As String(,) = New String(2, 1) {}
TimeServers(0, 0) = "time-b.timefreq.bldrdoc.gov"
TimeServers(0, 1) = "132.163.4.102"
TimeServers(1, 0) = "time-c.timefreq.bldrdoc.gov"
TimeServers(1, 1) = "132.163.4.103"
TimeServers(2, 0) = "utcnist.colorado.edu"
TimeServers(2, 1) = "128.138.140.44"

Dim portNum As Integer = 13
Dim hostName As String
Dim bytes As Byte() = New Byte(1023) {}
Dim bytesRead As Integer = 0
Dim client As New System.Net.Sockets.TcpClient()
For i As Integer = 0 To 2
    hostName = TimeServers(i, 1)
    Try
        client.Connect(hostName, portNum)
        Dim ns As System.Net.Sockets.NetworkStream = client.GetStream()
        bytesRead = ns.Read(bytes, 0, bytes.Length)
        client.Close()

        Exit For
    Catch generatedExceptionName As System.Exception
    End Try
Next
Dim sp As Char() = New Char(0) {}
sp(0) = " "c
Dim dt As System.DateTime = New DateTime()
Dim str1 As String
str1 = System.Text.Encoding.ASCII.GetString(bytes, 0, bytesRead)

Dim s As String()
s = str1.Split(sp)
dt = System.DateTime.Parse(s(1) & " " & s(2))
'得到标准时间
dt = dt.AddHours(8)
'得到北京时间
Dim getdate As Date
getdate=dt.Date
Return getdate

帮我看看代码 有没有错

代码发上来了 帮我看一下 错在哪里 多谢
