sql - Using Oracle and C#, how can I pass in an array of numbers?

Question

This was my attempt:

cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add("i_num_array_price_list", OracleDbType.Decimal, myItems.Select(c => c.Price).ToArray(), ParameterDirection.Input);

In oracle, the type is declared as:

i_num_array_price_list IN num_array,

and that is defined as:

TYPE Num_Array IS VARRAY(10) OF NUMBER;

I've tried it as OracleDbType decimal and array, neither worked. Decimal produces this error:

Unable to cast object of type 'System.Decimal[]' to type 'System.IConvertible'.

Any idea how I can get it to accept my array of decimal values?

我找不到使用上述数组定义来完成这项工作的任何方法，因此我将其更改为关联数组并使用以下代码：

要定义我的数组： TYPE assoc_array_number_t IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;

要定义我的变量： i_num_array_price_list IN assoc_array_number_t

和我的 C# 代码：

cmd.Parameters.Add("i_num_array_price_list", OracleDbType.Decimal, myItems.Select(c => c.Price).ToArray(), ParameterDirection.Input).CollectionType = OracleCollectionType.PLSQLAssociativeArray;
