Static Class Method:

Answer 1

None of the above answers worked for me. I am building a .net core 2.1 api.

I used

public class Startup 
{
    public static string ConnectionString {get; private set;}


public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
           if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseHsts();
            }
            ConnectionString = Configuration.GetConnectionString("xxxxxx");
            app.UseMvc();
}

Then whenever i need it i call string ConnString = Startup.ConnectionString;
