ORA-01036 error on update query using c#

I am getting error when I update a number and try to get back that number. I have already googled for this error but all codes suggest the same solution I have but still I get this error.

Oracle.DataAccess.Client.OracleException ORA-01036: illegal variable
name/number at Oracle.DataAccess.Client.OracleCommand.ExecuteNonQuery()

Here is my C# code:

//add one to sequence and update it
query = "update unique_sequences " +
    "set last_sequence_number=last_sequence_number + 1 " + 
    "where unique_sequence_table_name='person' " +
    "returning last_sequence_number into :outnumber";
command.CommandText = query;
OracleParameter last_number = new OracleParameter("outnumber", OracleDbType.Varchar2, 13);
last_number.Direction = ParameterDirection.Output;

command.Parameters.Add(last_number);
command.ExecuteNonQuery();

where last_sequence_number is VARCHAR2(13 BYTE).

Thank you in advance.

You need to use different ParameterDirection Use:

last_number.Direction = ParameterDirection.ReturnValue;
