问题 I'm trying to create a generic function which calls another function with an any type parameter. This is what I tried: static GetInstance<T>(): T { return <T>injector.get(T); // get(param: any): any } The problem is this doesn't compile. I'm getting Cannot find name 'T' error. I tried get(typeof T) but typeof T is string "function" . What can I do? For clarification: get() method accept types. For example you can use it like this: import { MyService } from '..' constructor(){ let val = this

I build my project with dotnet build , targeting netcoreapp3.1 . The problem is that the assemblies contain the full path to the source-files: /home/runner/my-app/App.fs This means that the hash of the assemblies depends on the directory where the code was built. I want it to only depend on the hash of the source-files and the .NET SDK itself

问题 I have read this post. But when I tried: printf("before null %c after null\n", 0); // (ASCII=0) != '\0' ?? instead of getting: before null I got: before null after null So my question is: Is ASCII value 0 actually equal to '\0'? 回答1: Is ASCII value 0 actually equal to \0 ? Yes The differences in how the strings are stored in memory and handled by functions like printf() are important. "before null %c after null\n" "before null \0 after null\n" Both are stored in memory with an implicit \0
