是否有可能创建类型的一般方法T,其中T具有特定属性？

例如:

public static XmlDocument SerializeObjectToXml<T>(T obj)
{
    //...
}

我想只序列化一个带有Serializable和/或DataContract属性的类:

[Serializable]
[DataContract(Name = "viewModel", Namespace = "ns")]
internal class ViewModel
{
    //...
}

我有一个简单的钻取图表:jsfiddle

根据表中选定的值,我需要动态单击此图表中的特定列.我怎样才能做到这一点？我找到了如何点击图例区域,但没有点击列.

我试图在特定列上触发单击事件,但这样就不起作用了:

$('rect:not(:first):nth-child(1):first').click()

我认为必须隐藏在图表api中,但我看不到它在哪里.

这是否可以使用带有nhibernate linq的let关键字？我写

 var posts = from post in postsRepository.GetPosts(name)
             let commentsCount = (from c in NHUnitOfWork.CurrentSession.Linq<Comment>()
                                  where c.Post.ID == post.ID
                                  select c).Count()
             select new ...

作为回应我有

NHibernate.QueryException:无法解析属性:post:Sys.Domain.Entities.Post

我正在我的asp.net mvc 5应用程序中使用压缩和缓存机制.

我正在发送带有以下缓存标头的文件:

            Response.Cache.SetCacheability(HttpCacheability.Public);
            Response.Cache.SetExpires(DateTime.UtcNow.AddYears(1).ToUniversalTime());
            Response.Cache.SetLastModified(System.IO.File.GetLastWriteTime(serverPath).ToUniversalTime());
            Response.AppendHeader("Vary", "Accept-Encoding");

IE11,Edge,Firefox,都在F5刷新时发送If-Modified-Since标头,但不是Chrome.为什么这样以及如何解决它？在Chrome中,我获得了200个状态代码,文件从缓存中加载.

我遇到的第二个问题是启用gzip压缩.我有一个标准的动作过滤器:

public class CompressContentMvcAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            GZipEncodePage();
        }

        private bool IsGZipSupported()
        {
            string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"];

            if (!string.IsNullOrEmpty(AcceptEncoding) &&
                    (AcceptEncoding.Contains("gzip") || AcceptEncoding.Contains("deflate")))
            {
                return true;
            }

            return false;
        }

        private void GZipEncodePage()
        {
            HttpResponse Response = HttpContext.Current.Response;

            if (IsGZipSupported())
            {
                string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"];

                if (AcceptEncoding.Contains("gzip"))
                {
                    Response.Filter = //new GZipCompressionService().CreateCompressionStream(Response.Filter);
                        new System.IO.Compression.GZipStream(Response.Filter,
                                                System.IO.Compression.CompressionMode.Compress);
                    Response.Headers.Remove("Content-Encoding");
                    Response.AppendHeader("Content-Encoding", "gzip");
                }
                else
                {
                    Response.Filter =// new …

我在win 7上用winforms(.net 4.0)编写了一个简单的应用程序.应用程序看起来我想要的但是当我在windows xp上尝试它时,一切看起来都不一样.

我创建了一个示例示例,以展示它在win 7和xp上的外观.我可以做些什么来在两个系统上看到相同的外观？问题不仅在于背景和字体颜色,还在于控件.在这里,我展示了数字版本的外观,但是对于表格布局我也有问题.

 private void InitializeComponent()
    {
        this.numericUpDown1 = new System.Windows.Forms.NumericUpDown();
        this.groupBox1 = new System.Windows.Forms.GroupBox();
        ((System.ComponentModel.ISupportInitialize)(this.numericUpDown1)).BeginInit();
        this.SuspendLayout();
        // 
        // numericUpDown1
        // 
        this.numericUpDown1.DecimalPlaces = 2;
        this.numericUpDown1.Increment = new decimal(new int[] {
        1,
        0,
        0,
        131072});
        this.numericUpDown1.Location = new System.Drawing.Point(21, 26);
        this.numericUpDown1.Maximum = new decimal(new int[] {
        1,
        0,
        0,
        0});
        this.numericUpDown1.Name = "numericUpDown1";
        this.numericUpDown1.Size = new System.Drawing.Size(54, 22);
        this.numericUpDown1.TabIndex = 0;
        // 
        // groupBox1
        // 
        this.groupBox1.Location = new System.Drawing.Point(21, 82);
        this.groupBox1.Name = "groupBox1";
        this.groupBox1.Size = new System.Drawing.Size(226, 99); …

我想获得输出两个项目符号列表,如图所示:

但我得到的是这两个列表都有第二个(黑色圆圈)皮肤.

我的代码:

private static void AddNumberingDefinition(WordprocessingDocument docx)
        {
            NumberingDefinitionsPart numberingPart =
  docx.MainDocumentPart.AddNewPart<NumberingDefinitionsPart>();

            Numbering element =
              new Numbering(
                //     new Nsid(){ Val="FFFFFF80"},
                new AbstractNum(new Nsid() { Val = "FFFFFF80" },
                    new MultiLevelType() { Val = MultiLevelValues.HybridMultilevel },
                new TemplateCode() { Val = "4970B4E6" },
                  new Level(
                    new NumberingFormat() { Val = NumberFormatValues.Bullet },
                    new LevelText() { Val = "°" },//char.ConvertFromUtf32(61616) }
                    new LevelJustification() { Val = LevelJustificationValues.Left }//,
                //  new RunProperties() { RunFonts = new RunFonts() { Hint = FontTypeHintValues.Default, …
