Asp.Net C# DllImport problem

I want to import DLL file in my web site project. I have dll file "my.dll" in folder C:DLLDir and I'm using the code : [DllImport("C:\DLLDir\my.dll", EntryPoint = "Out32")] This works ok.

.NET Load assemblies at runtime Again

I posted a similar question a time ago. I need to load an assembly at runtime. This is easy if I know the absolute path of the dll at runtime. But I dont :( The assembly.Load() or LoadFromFile() fails if the file is not in the application root. The only thing I have is the dll name. The dll could be located in the root, system32 or in even in the GAC. Is it possible for .net to automati

.NET在运行时加载程序集再次

我前一段时间发布了类似的问题。 我需要在运行时加载程序集。 如果我知道运行时dll的绝对路径,这很容易。 但我不:(如果文件不在应用程序根目录下,assembly.Load()或LoadFromFile()失败。 我唯一拥有的就是dll的名字。 该DLL可能位于根,system32或甚至在GAC中。 .net是否可以自动确定dll的位置,例如:它应该先查看根目录。 如果没有移动到系统文件夹,请尝试GAC。 EDITED 我正在使用插件架构。 我不需要

Where in Query with Array in LINQ

I have array number = {2,3,4,5,6} Now i have to select rows from table "dtlRecord" where this number is a column. Number count 2 10 3 23 4 20 So what i need is select sum(count) from dtlRecord where number in (2,3,4,5,6) group by number I need above query in LINQ to SQL How about just using inner join: int[] numbers = new[] { 2, 3, 4, 5, 6 }; from r in dtlRecord

Accessing Microsoft.Win32.UnsafeNativeMethods?

Microsoft has a very nice Windows API wrapper included in .NET framework. It is stored in Microsoft.Win32.UnsafeNativeMethods , Microsoft.Win32.SafeNativeMethods and Microsoft.Win32.NativeMethods .Unfortunately they aren't accessible because they are declared as private. Is there a way of accessing them easily? Most method definitions in those classes (if not all) are extern declarations

访问Microsoft.Win32.UnsafeNativeMethods?

微软在.NET框架中包含一个非常漂亮的Windows API包装器。 它存储在Microsoft.Win32.UnsafeNativeMethods , Microsoft.Win32.SafeNativeMethods和Microsoft.Win32.NativeMethods中。很遗憾,它们不可访问,因为它们被声明为私有。 有没有办法轻松访问它们? 这些类中的大多数方法定义(如果不是全部)是使用DllImport属性的extern声明,这些属性通过P / Invoke引用Windows API中的函数。 这些声明所在的地方并不重要。 您
