How to convert a C char array to VB.NET

[Guest]

I'm testing a VoIP application, and I can't figure out how to dump
this into a Udpclient.send function. Thanks for any help, pointers...

How do I convert the array below to VB.NET? --

unsigned char grq[] = {
0x03, 0x20, 0x00, 0x00, 0x06, 0x00, 0x08, 0x91, 0x4a,
0x00,
0x02, 0x00, 0x0a, 0x60, 0x86, 0x48, 0x01, 0x86, 0xf8,
0x72,
0x04, 0x02, 0x01, 0x03, 0x85, 0x01, 0x40, 0x00, 0xc0,
0xa8,
0x0b, 0x16, 0xc0, 0x94, 0x02, 0x00, 0x01, 0x01, 0x80,
0x43,
0x36, 0x0c, 0x30, 0x02, 0x01, 0x10, 0x11, 0x02,

};
