具有Knockout和boolean的复杂对象映射

Question

try
        {
            string Ext = Path.GetExtension(Constants.XlFile);
            string connectionString = "";
            if (Ext == ".xls")
            {   //For Excel 97-03
                connectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source =" + Constants.XlFile + "; Extended Properties = 'Excel 8.0;HDR=YES'";
            }
            else if (Ext == ".xlsx")
            {    //For Excel 07 and greater
                connectionString = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source =" + Constants.XlFile + "; Extended Properties = 'Excel 8.0;HDR=YES'";
            }
            OleDbConnection conn = new OleDbConnection(connectionString);
            OleDbCommand cmd = new OleDbCommand();
            OleDbDataAdapter dataAdapter = new OleDbDataAdapter();
            cmd.Connection = conn;
            conn.Open();
            DataTable dtSchema;
            dtSchema = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
            string ExcelSheetName = dtSchema.Rows[0]["TABLE_NAME"].ToString();
            conn.Close();
            //Read all data of fetched Sheet to a Data Table
            conn.Open();
            cmd.CommandText = "SELECT * From [" + ExcelSheetName + "]";
            dataAdapter.SelectCommand = cmd;
            dataAdapter.FillSchema(dt, SchemaType.Source);
            dt.Columns[0].DataType = typeof(String);
            dt.Columns[1].DataType = typeof(String);
            dt.Columns[2].DataType = typeof(String);
            dt.Columns[3].DataType = typeof(String);
            dt.Columns[4].DataType = typeof(DateTime);
            dt.Columns[5].DataType = typeof(String);
            dt.Columns[6].DataType = typeof(String);
            dt.Columns[7].DataType = typeof(String);
            //dataGrid2.Columns[4].CellTemplate.ValueType = typeof(DateTime);
            dataAdapter.Fill(dt);
            dataGrid2.DataSource = dt;

            conn.Close();

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

所以我在

时处理与此对象的绑定

data1 : {
    id : 10,
    name : 'franck',
    param:{
        style:'desert'
        isUsed : true,
    },
};

在KnockOut文件中，如果出现：

var rawValue = valueAccessor() 

2小时后，我发现属性以“ param ___” +我的专有名称开头，因为经典的param.style无法正常工作。

下面的代码仅在布尔属性上发生...也许KO有一个特殊的布尔名称吗？

data-bind = "value : id" // all is OK is an Observable
data-bind = "value : param___style" // all is OK is an Observable

对不起，我的英语不好。
