我花了很多时间调查这个问题，即使我在这个网站上发现很少有类似的帖子但没有用。

如果有人可以帮助我。

以下是例外情况：

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

C#代码：

public static List<CHPGroupishObject> ConnectThirdPartyOracleDBForData(string connectionstring, string SPName, string Filter, string Param2, string Param3, string Param4)
    {
        DataSet result;
        List<CHPGroupishObject> lstCHPGroupishObject = new List<CHPGroupishObject>();
        CHPGroupishObject cHPGroupishObject = null;
        try
        {
            DbMain objDbHandler = new DbMain(connectionstring);
            RetResult resultObject = new RetResult();
            ArrayList colParams = new ArrayList();
            OracleParameter param = new OracleParameter("Filter", OracleType.VarChar, 300, ParameterDirection.Input, "", DataRowVersion.Default, true, Filter);
            colParams.Add(param);
            param = new OracleParameter("Param2", OracleType.VarChar, 300, ParameterDirection.Input, "", DataRowVersion.Default, true, Param2);
            colParams.Add(param);
            param = new OracleParameter("Param3", OracleType.VarChar, 300, ParameterDirection.Input, "", DataRowVersion.Default, true, Param3);
            colParams.Add(param);
            param = new OracleParameter("Param4", OracleType.VarChar, 300, ParameterDirection.Input, "", DataRowVersion.Default, true, Param4);
            colParams.Add(param);
            param = new OracleParameter("RefCursor", OracleType.Cursor, 4000, ParameterDirection.Output, "", DataRowVersion.Default, true, null);
            colParams.Add(param);
            result = objDbHandler.ExecuteProcedure(SPName, "GARSAccount", ref colParams);
            foreach (DataRow row in result.Tables[0].Rows)
            {
                cHPGroupishObject = new CHPGroupishObject();
                cHPGroupishObject.dn = row["EntitlementCode"].ToString();
                cHPGroupishObject.Name = row["EntitlementName"].ToString();
                lstCHPGroupishObject.Add(cHPGroupishObject);
            }
            return lstCHPGroupishObject;
        }
        catch (Exception ex)
        {
            return null;
        }
    }

好的得到我的答案！

String 是可为空的类型，如果我们将空字符串传递给它，SQL Server 接受，但 Oracle 不接受。

在这里，Param2 传递了 null，因此它给出了一个错误。
