How to create get dynamic string interpolation string in C#

Sakthikumar Thanavel

Hi Guys, The below code used to interpolate the string and it is configured in the coding itself.

string Name = "Sakthi";

Console.WriteLine($"Name: {Name}");

Output:

Name: Sakthi

My Need is, I want to configure the interpolation expression in the configuration file and need to show the result after interpolation.

Configuration:

Code:

Console.WriteLine(configurationManager.AppSettings["dataToInterpolate"]);

Expected Result:

Name: Sakthi

For this, We can use string.Format() method. But we want to supply the value explicitly. I am trying to do it dynamically like angular js binding. Can anyone help on this.

You can easily use the features like we have in Mail Merge. 1. Suppose you have a sentence 'Hello @@name, how are you' 2. Allow user to provide a replacement word like @@name with 'aakash' 3. It seems, all done just replace all the word having @@xxxx with the replaced word.

Ideally it will give following Result:

Name: {Name}

You can do one tricky thing using Replace as like following to retrieve our expected result

Console.WriteLine(System.Configuration.ConfigurationSettings.AppSettings["dataToInterpolate"].Replace("{Name}", Name));

Result:

Name: Sakthi

I hope this will help
