我正在寻找一个很好的教程，在 WinForm 应用程序中使用 NHibernate 配置 AUTOFAC，在创建表单时注入 ISession 并在表单关闭时处置 ISession。

我发现了很多 MVC 和 ASP.NET 示例，但没有一个使用 WinForm。

你能为我指出正确的方向吗？

我在WinForm应用程序中使用Windsor Castle和log4net时出现此错误.

错误:

Could not convert from 'Castle.Services.Logging.Log4netIntegration.Log4netFactory,Castle.Services.Logging.Log4netIntegration,Version=2.5.1.0, Culture=neutral,PublicKeyToken=407dd0808d44fbdc' to System.Type - Maybe type could not be found

我想用ITextSharp创建以下PDF布局:

我使用以下代码生成我的表:

Document document = new Document(PageSize.A4);
MemoryStream memoryStream = new MemoryStream();

PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);

document.Open();

PdfPCell cell;
PdfPTable table = new PdfPTable(2);

table.SetWidths(new float[] { 450, 100 });
table.WidthPercentage = 100;

cell = new PdfPCell(new Phrase("Item cod werwerwer"));
table.AddCell(cell);

cell = new PdfPCell(new Phrase("100"));
table.AddCell(cell);

cell = new PdfPCell(new Phrase(string.Empty));
table.AddCell(cell);

cell = new PdfPCell(new Phrase("100"));
table.AddCell(cell);

document.Add(table);

writer.CloseStream = false;
document.Close();
memoryStream.Position = 0;

return memoryStream.ToArray();

如何在不使用固定高度值的情况下强制表格覆盖整页高度？

我在NHibernate中有类似这样的映射情况:

ClassA
mapping.Id(x => x.Id).Column("rowid").GeneratedBy.Identity().Unique();

ClassB
mapping.Id(x => x.Id).Column("rowid").GeneratedBy.Identity().Unique();
mapping.References<ClassA>(x => x.ClassA).Nullable();

当NHibernate生成数据库模式时,即使我在映射声明中指定了"Nullable"属性,它也会在这些表之间创建一个外键.很明显,如果我尝试保存我的对象,我会得到一个外键约束错误,如果我从数据库中手动删除外键,它就像一个魅力.

如何告诉NHibernate不要在这种情况下创建外键脚本？

我Identity Server 4在我的Angular 5应用程序中使用。

我以这种方式配置了身份服务器：

  public static IEnumerable<Client> GetClients()
        {
            return new List<Client>
            {
                new Client
                {
                    ClientId = "client",
                    AllowedGrantTypes = GrantTypes.ResourceOwnerPassword, 
                    AllowAccessTokensViaBrowser = true,
                    RequireClientSecret = false, 

                    AllowedScopes = {
                        "api1"
                    },

                    AllowedCorsOrigins = new List<string>
                    {
                        "http://localhost:4200"
                    } 
                }
            };
        }


    public void ConfigureServices(IServiceCollection services)
    {

        var cors = new DefaultCorsPolicyService(_loggerFactory.CreateLogger<DefaultCorsPolicyService>())
        {
            AllowedOrigins = { "http://localhost:4200" }
        };
        services.AddSingleton<ICorsPolicyService>(cors);

        services.AddIdentityServer()
                .AddDeveloperSigningCredential()
                .AddInMemoryApiResources(Config.GetApiResources())
                .AddInMemoryClients(Config.GetClients());
    }

这是我的 Angular 配置：

export const oAuthDevelopmentConfig: AuthConfig = { …

我有这个使用ControlValueAccessor. 该组件有自己的内部表单，我找不到在哪里设置表单控件的初始值。

有人可以指出我正确的方向吗？

import {
  Component, ChangeDetectorRef, forwardRef,
  NgModule, OnInit} from '@angular/core';
import { FormGroup, FormControl, FormBuilder } from '@angular/forms';
import { NG_VALUE_ACCESSOR, ControlValueAccessor } from '@angular/forms';
import { CommonModule } from '@angular/common';
import { debounceTime } from 'rxjs/operators';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

export const ADDRESS_VALUE_ACCESSOR: any = {
  provide: NG_VALUE_ACCESSOR,
  useExisting: forwardRef(() => AddressFormComponent),
  multi: true
};


@Component({
  selector: 'app-address-form',
  templateUrl: 'address-form.component.html',
  providers: [ADDRESS_VALUE_ACCESSOR],
})
export class AddressFormComponent implements OnInit, ControlValueAccessor {

  addressForm: FormGroup; …

我使用这个javascript调整大小,最大为800px,页面上的大(5Mb)图像:

 <script type="text/javascript">
 $(document).ready(function () {
     $('.detailImg').each(function () {
         var maxWidth = 800; // Max width for the image
         var maxHeight = 800;    // Max height for the image
         var ratio = 0;  // Used for aspect ratio
         var width = $(this).width();    // Current image width
         var height = $(this).height();  // Current image height

         // Check if the current width is larger than the max
         if (width > maxWidth) {
             ratio = maxWidth / width;   // get ratio for scaling …

我使用 scrollTop JQuery 函数有一种奇怪的行为。我有一个包含复杂文本的 div，它分为不同的部分，如下所示：

<div id="wrapper" ... >
    <div id="section1">
        <h1>Section 1</h1>
        Lorem ipsum dolor sit amet, consectetuer... 
        ...
    </div>
    <div id="section2">
        <h1>Section 2</h1>
        Lorem ipsum dolor sit amet, consectetuer... 
        ...
    </div>
    <div id="section3">
        <h1>Section 3</h1>
        Lorem ipsum dolor sit amet, consectetuer... 
        ...
    </div>
    ...

第二个 DIV 包含一个简单的部分列表，当用户单击每个部分时，我希望包装器滚动到右侧部分：

<li>
   <a href="#" onclick="customScrollTo('section1')">section1</a>
</li>
<li>
   <a href="#" onclick="customScrollTo('section2')">section2</a>
...

这是简单的 JS 函数：

function customScrollTo (section) {

     $('#wrapper').animate({
         scrollTop: $("#wrapper div[id='" + section + "']").offset().top
     }, 200);
};

现在，如果您尝试在此 JSfiddle 中对其进行测试： …
