问题 In the .NET Framework 4.6.2 Microsoft added support for persisted-key symmetric encryption using a CNG key storage provider and the AesCng algorithm. The documentation for instantiating the AesCng class using an existing key is pretty clear - just pass the key name into the constructor. But how do I generate a new persisted key to use for AES encryption? I can't find the instructions in the release notes or the documentation. Is this even possible from C#? 回答1: While not documented well, this

问题 I want to retrieve some data with an HttpWebRequest (GET): var request = (HttpWebRequest)WebRequest.Create(myUri); request.Timeout = 5 * 60 * 1000; request.ReadWriteTimeout = 5 * 60 * 1000; // request.ServicePoint.SetTcpKeepAlive(true, 5 * 1000, 1000); var response = request.GetResponse(); Unfortunately the computation on the server can take two or more minutes. So between me sending the header and finally receiving the data in the response stream the socket connection is idle. With curl or a

问题 I need to upload a file to SFTP server. I am using VB.NET 2008. How can I upload a simple .csv file from my local computer to SFTP server using port number, user name and password, etc? Thanks in advance. 回答1: A commonly used open source SFTP library for .NET is SSH.NET. With it, you can use a code like this: Dim client As SftpClient = New SftpClient("example.com", "username", "password") client.Connect() Using stream As Stream = File.OpenRead("C:\local\path\some.csv") client.UploadFile

问题 Hi guys I am trying to create an ASP.net Core 2.0 web application; I have placed the static files in a folder called Content.

问题 I'm using TPL dataflow to process items off a queue in an Azure worker role. Should I have a single long running dataflow, or spawn a new flow for every messages I receive? If an error is thrown in a block, that block will stop accepting new messages. That means if there is an exception in a block, the whole dataflow will stop processing. I need to be able to withstand exception from something like invalid queue inputs without locking my dataflow. I see one of two options: I have a start a

问题 I have recently installed Enterprise library 5.0 but I am unable to find "Microsoft.Practices.ObjectBuilder2.dll". I am working on CALTutorial where I will need this dll as reference. Can anybody answer this? Thanks, Omky 回答1: There is breaking change in EntLib 5. The library help file mentioned about this which says that code for "Microsoft.Practices.ObjectBuilder2.dll" is included in Unity assembly hence no need of separate reference. 回答2: In case anyone else has a similar issue, I am

问题 I'm mainly working in Spyder, building scripts that required a pop-up folder or file Browse window. The code below works perfect in spyder. In Pycharm, the askopenfilename working well, while askdirectory do nothing (stuck). But, if running in debug mode - the script works well. I tried to run the script from SAS jsl - same issue. Any Idea what should I do? Python 3.6 Pycharm 2017.2 Thanks. The Code I'm using includes: import clr #pythonnet 2.3.0 import os import tkinter as tk from tkinter

问题 I have a dll which is based on .net 3.5 -- it uses internally for example Linq, but the exposed API is straightforward, no fancy stuff. Since C# generics are resolved at compile time I assume that for calling party all it counts is API (all public parts). However when I try to use this dll from net2.0 project I get info, that the dll cannot be referenced because the dll or one of its dependencies requires a later version of .net framework. I can install any .net version I want on target
