如何在不使用length()String类方法的情况下找到String的长度？

如果我在末尾有任何带有图像文件的URL,例如:

http://www.google.com/image1.jpg
http://www.google.com/test/test23/image1.jpg

我想得到:

image1.jpg

在C#中执行此操作的最佳方法是什么？

我的一个项目解决方案在我安装VS 2013的系统上工作正常.但是当我在VS 2015中的另一个系统上打开相同的项目时,它会给出这个引用错误:

错误CS1703已导入具有等效标识的多个程序集:'D:\ src\packages\Microsoft.Bcl.1.1.10\lib \net40\System.IO.dll'和'C:\ Program Files(x86)\ Reference

大会\微软\ Framework.NETFramework\V4.5 \外立面\ System.IO.dll".删除其中一个重复的引用.

项目文件引用包文件,但是当它在VS中打开时,它会自动转换为Framework库路径.我无法卸载BCL包,因为它是其他包的依赖项.

编辑:

为什么解决方案在一个版本的Visual Studio中构建良好,但它在另一个版本中提供了多个程序集错误？

有没有办法解决这个问题,以便它可以在不同的版本中工作？

我也有这个问题,但他的解决方案在VS 2017中完美构建,但它无法在VS 2015上构建.

我有一个带有KeyPressed事件的TextBox,我想使用jquery/javascript在该事件上过滤GridView.

<asp:TextBox ID="txtSearch" runat="server" OnKeyPressed="txtSearch_KeyPressed()">
</asp:TextBox>

<script>
  function txtSearch_KeyPressed()
  {
      // gvBanquet is an ID of GridView and SearchBanquet method returns a DataTable
      gvBanquet.DataSource = DLBqt.SearchBanquet(txtSearch.Text.Trim());
      gvBanquet.DataBind();
  }
</script>

请注意,GridView绑定代码来自.CS文件:

gvBanquet.DataSource = DLBqt.SearchBanquet(txtSearch.Text.Trim());
gvBanquet.DataBind();

我不知道它会如何起作用？它应该在TextBox的按键上绑定.

编辑:我找到了OnTextChangedTextBox 的解决方案服务器站点事件,它在按下Enter而不是按键后绑定GridView .

<asp:TextBox ID="txtSearch" runat="server" OnTextChanged="txtSearch_TextChanged" 
    AutoPostBack="True" ></asp:TextBox>

protected void txtSearch_TextChanged(object sender, EventArgs e)
{
    gvBanquet.DataSource = DLBqt.SearchBanquet(txtSearch.Text.Trim());
    gvBanquet.DataBind();
}

我不希望它与OnTextChanged事件,但我认为它将使用JavaScript或jQuery的 keypressed事件,所以我不知道该怎么办？

更新:我已尝试下面的jQuery代码按键在文本框中按,但它也无法正常工作.

$(document).ready(function () {

    $('#txtSearch').on("keyup", function () {
        // could bind …

如何禁用？

在下面的屏幕截图中,您可以看到所有以ServiceHub开头的六个进程.这些从我开始VS-2017 CE开始.令人讨厌的是,当我退出VS-2017 CE时,它们并没有停止.我想知道如何禁用它们,以便它们不会首先启动.

如何启用？

什么打开这些？

在一个没有编译的旧webform 站点项目中esclude使用管道中的aspx页面有一种方法吗？nancy.Owin

当我将nancy配置为post-back并且请求是一个aspx页面时,将删除post-back,因为nancy删除它并调用该页面.

public void NancyConfig(IAppBuilder app)
{
    app.UseNancy(options =>
    {
        options.Bootstrapper = new MyBootstrapper();
        options.PerformPassThrough = (context => context.Response.StatusCode == HttpStatusCode.NotFound);
    });

    app.UseStageMarker(PipelineStage.MapHandler);
}

在options.PerformPassThrough擦后门柱的内容和调用页面.因为没有回发是好的,但是在后期详细说明中,这呈现出无限循环.

如何NancyFx在passtrought选项中配置不擦除回发？

这是android studio 3.0上的错误的屏幕截图:

我收到这些错误:

错误:找不到资源drawable/abc_ic_ab_back_mtrl_am_alpha(又名com.instacoin:drawable/abc_ic_ab_back_mtrl_am_alpha).

错误:链接文件资源失败.

错误:java.util.concurrent.ExecutionException:java.util.concurrent.ExecutionException:com.android.tools.aapt2.Aapt2Exception:AAPT2错误:检查日志以获取详细信息

错误:任务':app:processDebugResources'的执行失败.无法执行aapt

这是我的AndroidManifest:

我正在尝试生成签名的apk但我收到以下错误.

我搜索过它,但没有找到任何可以解决这个问题的东西.

解决方案我试过了

• 无效缓存/重启

• 删除.gradle文件夹

• 卸载android studio

我最近更新了最新版本3.0.1的工作室,它工作正常,但问题从最近几天开始.

请有人帮我这个!
