This is code for executing stored procedures with and with out parameters via reflection. Do note that the objects property names need to match the parameters of the stored procedure.

private static string ConnString = ConfigurationManager.ConnectionStrings["SqlConnection"].ConnectionString;
    private SqlConnection Conn = new SqlConnection(ConnString);

    public void ExecuteStoredProcedure(string procedureName)
    {
        SqlConnection sqlConnObj = new SqlConnection(ConnString);

        SqlCommand sqlCmd = new SqlCommand(procedureName, sqlConnObj);
        sqlCmd.CommandType = CommandType.StoredProcedure;

        sqlConnObj.Open();
        sqlCmd.ExecuteNonQuery();
        sqlConnObj.Close();
    }

    public void ExecuteStoredProcedure(string procedureName, object model)
    {
        var parameters = GenerateSQLParameters(model);
        SqlConnection sqlConnObj = new SqlConnection(ConnString);

        SqlCommand sqlCmd = new SqlCommand(procedureName, sqlConnObj);
        sqlCmd.CommandType = CommandType.StoredProcedure;

        foreach (var param in parameters)
        {
            sqlCmd.Parameters.Add(param);
        }

        sqlConnObj.Open();
        sqlCmd.ExecuteNonQuery();
        sqlConnObj.Close();
    }

    private List GenerateSQLParameters(object model)
    {
        var paramList = new List();
        Type modelType = model.GetType();
        var properties = modelType.GetProperties();
        foreach (var property in properties)
        {
            if (property.GetValue(model) == null)
            {
                paramList.Add(new SqlParameter(property.Name, DBNull.Value));
            }
            else
            {
                paramList.Add(new SqlParameter(property.Name, property.GetValue(model)));
            }
        }
        return paramList;

    }
