vb.netbyte vbnetbyte转成string

vb.net byte数组中怎样搜索特定的byte值Public Class Form1
【vb.netbyte vbnetbyte转成string】Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a() As Byte = System.IO.File.ReadAllBytes("record.db")
For Index As Integer = a.GetLowerBound(0) To a.GetUpperBound(0) - 3
If a(Index) = 56 AndAlso a(Index + 1) = 57 AndAlso a(Index + 2) = 58 AndAlso a(Index + 3) = 59 Then
Debug.Print(Index.ToString) '输出byte串位置
End If
Next
End Sub
End Class
刚学,不知道有没有直接在数组中搜索一串元素的方法 。
vb.netbyte定义长度正确的方法如下:
Visual Basic 复制代码
Structure Person
Public ID As Integer
Public MonthlySalary As Decimal
Public LastReviewDate As Long
VBFixedString(15) Public FirstName As String
VBFixedString(15) Public LastName As String
VBFixedString(15) Public Title As String
VBFixedString(150) Public ReviewComments As String
End Structure
如何将VB.NET字符串转换成字节数组1、字节数组转换为字符串
byte[] byBuffer = new byte[20];
String strRead = new String(byBuffer);
strRead = String.copyValueOf(strRead.toCharArray(), 0, byBuffer.length]);
2、字符串转换成字节数组
byte[] byBuffer = new byte[200];
String strInput=abcdefg;
byBuffer= strInput.getBytes();
注意:如果字符串里面含有中文,要特别注意 , 在android系统下,默认是UTF8编码,一个中文字符相当于3个字节,只有gb2312下一个中文相当于2字节 。这种情况下可采取以下办法:
VB.net 错误 1 类型“Byte”的值无法转换为“Byte 的 1 维数组” 。怎么回事?没见过一次性给数组多个元素赋值的 , 只有在定义时可以初始数组元素,但不是圆括号
Dim addr As Byte = 0
Dim i As Byte = 0
Dim byteAddr As Byte = addr + i
Dim temp1 As Byte = Convert.ToByte(Hex(topV).Substring(2, 4))
Dim bytesnd() As Byte = {byteAddr, HAB, HCD, H1, HA, H2, H0, H0, temp1, temp2, H0, 0, 0, 0, 0, 0, 0, 0}
