小编use*_*838的帖子

我通过npm install flatpickr安装了flatpickr.日历显示就像点击输入控件一样

var React = require('React');
var ReactDOM = require('ReactDOM');
var Flatpickr = require('flatpickr');

var Calender = React.createClass({

    componentDidMount: function(){
    this.flatpickr = new Flatpickr(this.refs.date, {dateFormat: "m/d/Y"});
    },

    render: function() {
        return(
                <div>            
                    <input data-enable-time defaultValue='2016-11-11' ref="date_from" />    
                </div>
             );
    }
});

将以下行从C#转换为VB.Net时我得到了

表达式不会产生值

C#

query.ToList().ForEach(ti => cat.Add(ti));

VB.NET

query.ToList().ForEach(Function(ti) cat.Add(ti))

C#代码:

void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
    new DesignerMetadata().Register();

    var toolbox = new ToolboxControl();
    var cat = new ToolboxCategory("Standard Activities");
    var assemblies = new List<Assembly>();
    assemblies.Add(typeof(Send).Assembly);
    assemblies.Add(typeof(Delay).Assembly);
    assemblies.Add(typeof(ReceiveAndSendReplyFactory).Assembly);

    var query = from asm in assemblies
                from type in asm.GetTypes()
                where type.IsPublic &&
                !type.IsNested &&
                !type.IsAbstract &&
                !type.ContainsGenericParameters &&
                (typeof(Activity).IsAssignableFrom(type) ||
                typeof(IActivityTemplateFactory).IsAssignableFrom(type))
                orderby type.Name
                select new ToolboxItemWrapper(type);

    query.ToList().ForEach(ti => cat.Add(ti));
    toolbox.Categories.Add(cat);
    Grid.SetColumn(toolbox, 0);
    Grid.SetRow(toolbox, 1);
    LayoutGrid.Children.Add(toolbox);
}

我想要Vb.net转换.当我在vb.net中转换此代码时在query.ToList()中获取错误.ForEach(Function(ti)cat.Add(ti))此行.error是Expression不生成值.

转换VB.NET代码

  Private Sub MainWindow_Loaded(ByVal …
