急：C#源VB源
下面段C#的 winfrom源怎成VB言代，求助！！！
private void readcard()
{
byte[] byteuid = new byte[256];
byte[] byteBuffer = new byte[256];
string strErrorCode = "";
string strFlag = "";
int nFlag = 0;//卡类型不一样，0x42返回值带安全状态字节，0x02返回值不带安全状态字节
strFlag = "02";
int nRet =MiReader.ISO15693_Read(Convert.ToByte(strFlag), Convert.ToByte(textReadArea.Text), Convert.ToByte(textReadNum.Text), byteuid, byteBuffer);
}

MiReader方法：
[DllImport("mi.dll")]
public static extern int ISO15693_Read(byte flag, byte blk_add, byte num_blk, [In]byte[] uid, [In]byte[] buffer);

重要的是色部份的。。。多！！！

[解决办法]
Public Declare Function ISO15693_Read Lib "mi.dll" (ByVal flag As Byte, ByVal blk_add As Byte, ByVal num_blk As Byte, ByRef uid As Byte, ByRef buffer As Byte) As Long


[解决办法]

VB code

Private Function FormatErrorCode(ByRef bytes() As Byte) As StringSelect Case bytes(0)Case &H80    FormatErrorCode = "Success"Case &H81     FormatErrorCode = "Parameter Error"Case &H82     FormatErrorCode = "Communication TimeOut"Case &H83     FormatErrorCode = "Can't Find Card"Case Else     FormatErrorCode = "Command Error"End SelectEnd Function
