can instruction number be accessed in MSIL?

Hi,

I have got two questions.

1. Can instruction number that is number that appears before opcode that starts with IL_xxxx be accessed? If so how can it be accessed?

for example

IL_0017: callvirt Void [System.Data] System.Data.SqlClient.SqlConnection.Open()

i need to access the part marked with red background.

2. Also can the instruction number after Br statement be accessed?

for example

IL_003c: brfalse.sIL_0044

how can the part marked with red background accessed?

Thanks,
