刚入手VB.NET不知道怎么将数字转换成字节数组
Private Function Conver_Hex(ByVal L As Long) As Array
Dim str_L As String = Hex(L)
If str_L.Length \ 2 0 Then
str_L = "0" str_L
End If
Dim byt(str_L.Length / 2 - 1) As Byte
For i = 0 To str_L.Length / 2 - 1
byt(i) = Convert.ToByte(str_L.Substring(2 * i, 2), 16)
Next
Return byt
End Function
'下面是调用代码
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim L As Double = 123456
Dim byt() As Byte = Conver_Hex(L)
End Sub
VB 怎样将字符串转化为数值
最简单的就是直接转换，就是把字符串变量赋值给数值变量。\x0d\x0a数值变量=字符串\x0d\x0a\x0d\x0a如果必须转换，就使用 Val 函数赋值，会把字符串转换成双精度数。\x0d\x0a比如：数值变量=Val(字符串)\x0d\x0a例：\x0d\x0an = Val("3.5") ' 变量n赋值为3.5\x0d\x0a\x0d\x0a或者使用取整函数，也可以转换。\x0d\x0a比如：数值变量=Int(字符串) 或者 数值变量=CInt(字符串)\x0d\x0a例：\x0d\x0an = Int("3.5") ' 取整数，变量n赋值为3\x0d\x0a\x0d\x0an = CInt("3.5") ' 四舍五入取整数，变量n赋值为4
vb.net数组型转换为数字型
Dim byts1() As Byte = {255, 255, 0, 0}
'4位16进制数组转Integer
Dim value As Integer = BitConverter.ToInt32(byts1, 0)
'Integer转4位16进制数组()
Dim byts2() As Byte = BitConverter.GetBytes(value)
vb.net中如何将一行包含字母、标点、数字(可能是小数)的字符串转换为纯数字的数组？
string str1 = "a=1.2，3.5，7.88";
var arr = (from s in str1.Split('=')[1].Split('，') where s.Trim() != "" select Convert.ToDouble(s)).ToArray();
Split('，')这个地方逗号是全角还是半角的按照你文本内容里面的来
VB.NET如何把字符串（不全是数字或为空）转换成数字？
明白你的意思了,只要是字母都会转换成数字,帮你写好了("usernane"和 "pasward" 我这里写成 "username" 和" password"）
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim username, password As String
Dim temp As Long
Dim r As String = ""
Dim v As String = TextBox1.Text
For Each c In v.ToString
If IsNumeric(c) Then
r = c
Else
r = ((Asc(c) - 65).ToString("00"))
End If
Next
username = r
temp = username * 3 - 500
password = CStr(temp)
TextBox2.Text = password
End Sub
