问题 I am trying to read an image into Base64 format using .Net Core 2.2 and it throws ArgumentException: Image format is unknown. System.Drawing.Image.FromFile(string filename, bool useEmbeddedColorManagement) The filePath is correct, and I have double and triple checked that the file exists. I have attempted naming my PNGs with both upper and lowercase extension. This does not happen locally on windows, but once the application is deployed to linux is happens. The code in question is below.

问题 I have a .net core 2.0 program running on Linux (Ubuntu Server 16.04 LTS). I'm trying to shutdown the computer by invoking a process with the following command: sudo shutdown -h now , though when the program is running in the background as daemon service, the shutdown process does not work. Here is the code: var process = new Process { StartInfo = { CreateNoWindow = true, RedirectStandardError = true, RedirectStandardInput = true, RedirectStandardOutput = true, UseShellExecute = false,

问题 I am trying to create a .NET core application that connects to multiple databases, but using one generic repository that contains the logic for all CRUD operations. What is the best way to achieve this? public Repository(ApplicationDbContext dbContext) { _dbContext = dbContext; _set = _dbContext.Set<T>(); } Above is the constructor of my repository. Here, I inject the ApplicationDbContext. I am looking for a way to make this ApplicationDbContext generic, so I only have to need only one

问题 I am using the Novell LDAP library for making queries to an Active Directory from a .NET Code application. Most of the queries succeed, but some return more than 1000 results, which the AD server refuses. I therefore tried to find out how to page LDAP queries using Novell's library. The solution I put together looks like public IEnumerable<LdapUser> GetUsers() { this.Connect(); try { var cntRead = 0; // Total users read. int? cntTotal = null; // Users available. var curPage = 0; // Current

问题 We are running an intranet Application on .Net Core 2.0. Application insight is very helpfull to catch exceptions. So when the User comes up to us for support we would like to find his request that caused problems in application insight. I added an ClientIpHeaderTelemetryInitializer like this: public class CustomTelemetry : ClientIpHeaderTelemetryInitializer { private readonly IHttpContextAccessor _httpContextAccessor ; public CustomTelemetry(IHttpContextAccessor httpContextAccessor) : base

问题 I am trying to get video details (length, height, width, and content type) from a video based on a URL. By using the nuget package https://www.nuget.org/packages/NReco.VideoInfo.LT I was able to create an Azure Function running locally pointing to my local install of FFProbe rather easily. However, the trick is now making it compatible with an Azure Function and, to the best of my knowledge, the easiest way to do that is by providing a Docker image that contains everything needed (this would
