Oracle函数的.net类型参数错误

这是我的代码(我试图改变名称出于安全原因)

和这些

  cmd.Parameters.AddWithValue("M1", "24234234234").OracleType = OracleType.VarChar;
                cmd.Parameters.AddWithValue("N1", DateTime.Now.ToString("dd/MMM/yyyy")).OracleType = OracleType.DateTime;//'18/MAY/2015'
                cmd.Parameters.AddWithValue("O1", DateTime.Now.ToString("dd/MMM/yyyy")).OracleType = OracleType.DateTime;

这些参数的实际类型为:

A Numeric(2)
B Varchar(8)
C Varchar(40)
D Numeric(4)
E Numeric(4)
F Numeric(4)
G Numeric(6)
H Numeric(3)
I Numeric(1)
J Varchar(1)
K Varchar(35)
L Numeric(4)
M Numeric(3)
N Numeric(6)
O Numeric(8)
P Numeric(3)
Q Numeric(4)
R Numeric(3)
S Numeric(6)
T Numeric(8)
U Numeric(3)
V Varchar(35)
W Numeric(20,6)
X Varchar(3)
Y Varchar(255)
Z Numeric(1)
A1 Varchar(80)
B1 Varchar(80)
C1 Varchar(5)
D1 Varchar(50)
E1 Numeric(4)
F1 Numeric(4)
G1 Varchar(40)
H1 Varchar(40)
I1 Varchar(40)
J1 Varchar(40)
K1 Numeric(4)
L1 Varchar(1)
M1 Varchar(35)
N1 Datetime
O1 Date

i am getting error:

ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'my function name'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

i打印运行时参数的数量，它是41(正确)，所以错误的是这些类型之一。请帮忙，我已经试了两天了，但还没有成功。
