How to create Procedure with table variable as paramenter and call it from ADO.net

public static void saveProductPricing(DataTable ProductPricing)
{
    try
    {
        using (SqlConnection sqlConn = new SqlConnection(Common.ConnectionString))
        {
            sqlConn.Open();
            SqlCommand cmdExecute = new SqlCommand();

            cmdExecute.CommandText = "spSaveProductPricing";
            cmdExecute.CommandType = CommandType.StoredProcedure;
            cmdExecute.CommandTimeout = 0;
            cmdExecute.Connection = sqlConn;

            cmdExecute.Parameters.AddWithValue("@ProductPricing", ProductPricing);

            //Also works without below code
            cmdExecute.Parameters["@ProductPricing"].SqlDbType = SqlDbType.Structured;

            cmdExecute.ExecuteNonQuery();
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}
