filepath - absolute File path to relative file path

Question

I have a class library project (D:/projectName/SampleClassPrj) and a console application project D:/projectName/ConsolePrj. In class library project, a json file test.json and a class sample.cs (read and deserialise json) both present. d:/projectName/SampleClassPrj/test.json d:/projectName/SampleClassPrj/sample.cs

This works with absolute path like, d:/projectName/SampleClassPrj/test.json

but not working with relative path.

with relative path, by using file not found error as it is trying to find the file in the console (running) application assembly folder. D:/projectName/ConsolePrj/bin/test.json please help to find the solution

Answer 1

• first, check json file property "copy if newer".
• then, use Appdomain.CurrentDomain.BaseDirectory

string result = File.ReadAllText(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "ConnectionString.txt"));
