I need to pass an object to stored procedure for inserting the data..
I tried this coding

C#

button_click()
{
 insert_pro insobj = new insert_pro();
            insobj.ID = Convert.ToInt16(textBox1.Text);
            insobj.Name = textBox2.Text;
            insobj.Gender =Convert.ToChar(textBox3.Text);


            OracleConnection conn = new OracleConnection("Data Source=r2a;User ID=testv55;Password=testv55;");
            conn.Open();
            OracleCommand cmd = new OracleCommand("smp_ins", conn);
            cmd.CommandType = CommandType.StoredProcedure;
            OracleParameter emp_obj = new OracleParameter();
            emp_obj.OracleDbType = OracleDbType.Object;
            emp_obj.Direction = ParameterDirection.Input;
            emp_obj.UdtTypeName = "EMP_TYP";
            emp_obj.Value = insobj;
            cmd.Parameters.Add(emp_obj);

            cmd.ExecuteNonQuery();
            con.close();
}

insert_pro class:

C#

namespace test_form
{

 public  class insert_pro:IOracleCustomType
    {
        [OracleObjectMappingAttribute("Id")]
        public virtual int  ID { get; set; }

        [OracleObjectMappingAttribute("Name")]
        public virtual string Name { get; set; }

        [OracleObjectMappingAttribute("Gender")]
        public virtual char Gender { get; set; }


        public virtual void FromCustomObject(OracleConnection conn, IntPtr objUdt)
        {

            OracleUdt.SetValue(conn, objUdt, "Id", this.ID);
            OracleUdt.SetValue(conn, objUdt, "Name", this.Name);
            OracleUdt.SetValue(conn, objUdt, "Gender", this.Gender);

        }
        public virtual void ToCustomObject(OracleConnection conn, IntPtr objUdt)
        {
            this.ID = ((int)(OracleUdt.GetValue(conn, objUdt, "Id")));

            this.Name = ((string)(OracleUdt.GetValue(conn, objUdt, "Name")));

            this.Gender = ((char)(OracleUdt.GetValue(conn, objUdt, "Gender")));

        }
    }
}

error message is Custom type mapping for 'test_form.insert_pro' is not specified or is invalid

Where is the problem then?
Please post some code, what you've tried so far..

oracle part:

Create or replace type Employee1 as object
(id Number(10),
Name Varchar2(50),
Gender char(1)
);

/
Create or replace type Employee1_type is table of Employee1;

create or replace Procedure Employee_test(emp_obj Employee1_type)
is
L_Index BINARY_INTEGER:=1;
G_Employee1_type Employee1_type := Employee1_type();
begin
Insert into smp_try values (G_Employee1_type(L_Index).ID,
G_Employee1_type(L_Index).Name,G_Employee1_type(L_Index).Gender);
end;

C#

insert_pro insobj = new insert_pro();
insobj.ID = Convert.ToInt16(textBox1.Text);
insobj.Name = textBox2.Text;
insobj.Gender = textBox3.Text;

OracleConnection conn = new OracleConnection("Data Source=r2a;User ID=testv55;Password=testv55;");
conn.Open();
OracleCommand cmd = new OracleCommand("Employee_test", conn);
cmd.CommandType = CommandType.StoredProcedure;
OracleParameter objParam = new OracleParameter();
objParam.OracleDbType = OracleDbType.Object;
objParam.Direction = ParameterDirection.Input;
objParam.UdtTypeName = "Employee1";
emp_obj.Value = insobj;
cmd.Parameters.Add(emp_obj);
cmd.ExecuteNonQuery();
show_grid();
conn.Close();

inser_pro class:

public class insert_pro:IOracleCustomType
{
[OracleObjectMappingAttribute("id")]
public virtual int ID { get; set; }

[OracleObjectMappingAttribute("name")]
public virtual string Name { get; set; }

[OracleObjectMappingAttribute("gender")]
public virtual string Gender { get; set; }

public virtual void FromCustomObject(OracleConnection conn, IntPtr objUdt)
{

OracleUdt.SetValue(conn, objUdt, "id", this.ID);
OracleUdt.SetValue(conn, objUdt, "name", this.Name);
OracleUdt.SetValue(conn, objUdt, "gender", this.Gender);

}
public virtual void ToCustomObject(OracleConnection conn, IntPtr objUdt)
{
this.ID = ((int)(OracleUdt.GetValue(conn, objUdt, "ID")));

this.Name = ((string)(OracleUdt.GetValue(conn, objUdt, "name")));

this.Gender = ((string)(OracleUdt.GetValue(conn, objUdt, "gender")));

}

}

forget to create IOracleCustomTypeFactory

C#

[OracleCustomTypeMappingAttribute("TESTV55.SMP_EMP_TYPE")]
 
 public class ins_Factory : IOracleCustomTypeFactory
 {
    
     public virtual IOracleCustomType CreateObject()
     {
         insert_pro obj = new insert_pro();
           return obj;
     }
 
    
}
