Question

Is there a way to write to a spefic location in a text file? I would like to be able to create a template for an email as a text file then change the body based on different parameter values..

EmailBoby.txt..

This is an email body.

FirstName: [FirstName]
LastName: [LastName]

Can I in code locate [Firstname] and replace it with a value somehow?

Answer 1

Read the complete textfile into a string. Then do string replace and save again. Like that

string fileContent = File.ReadAllText(path);
fileContent.Replace("[FirstName]", "John");
File.WriteAllText(path, fileContent);
