学习JavaScript的最佳和最有效的书是什么？

什么是JavaScript数据类型？

我有一个错误:

错误2'int []'不包含'Contains'的定义,并且最好的扩展方法重载'System.Linq.Enumerable.Contains(System.Collections.Generic.IEnumerable,TSource)'有一些无效的参数

这是我的代码:

public partial class mymymy : System.Web.UI.Page
{
    int[] validType = { 2, 3, 4, 5, 6, 8, 13, 14, 16, 22 };

    protected void Page_Load(object sender, EventArgs e)
    {
    }

    protected void LinqDataSource_Selecting(object sender, LinqDataSourceSelectEventArgs e)
    {
        using (var dc = new soxMainDataContext())
        {
            var qry = from item in dc.LeaveRequests
                  where **validType**.Contains(item.Type)
                      && item.MgtApproval == null
                  select item;
            e.Result = qry;
        }
    }
}

如何DropDownList在ASP.NET中禁用？

码:

<asp:TemplateField HeaderText="Effective Total Hours"> 
<ItemTemplate> 
    <%# Eval("TotalHoursEffect")%> 
</ItemTemplate> 
<EditItemTemplate> 
    <asp:DropDownList ID="ddlEditTotalHoursEffect" AppendDataBoundItems="true" 
     DataSourceID="dsTHMsql" DataValueField="Minutes" Enabled="false" 
     ReadOnly="true" DataTextField="Display" 
     SelectedValue='<%# Eval("TotalHoursEffect") %>' runat="server"> 
        <asp:ListItem Selected="True" Value="">(Choose Minutes)</asp:ListItem>
    </asp:DropDownList> 
</EditItemTemplate> 
</asp:TemplateField>
