How To Write Input Param SqlInt32[] In CLR Store Procedure

hi,

I want to write a CLR store procedure like this:

public static void SetStateByBatch(SqlInt32[] ids)
{
using (SqlConnection conn = new SqlConnection("context connection=true"))
{
SqlTransaction tran = conn.BeginTransaction();
foreach (SqlInt32 id in ids)
{
try
{
conn.Open();
string commString = string.Format("update dbo.Notification set state=1 where noid='{0}'", id);
SqlCommand comm = new SqlCommand(commString, conn);
SqlContext.Pipe.ExecuteAndSend(comm);
}
catch
{
tran.Rollback();
}
}

tran.Commit();
conn.Close();
}

}

I'know that is not correct,how to resole this problem?

thanks in advance
