How to Dynamically Insert Into a Table Using a String with Entity Framework Core
In the world of software development, dynamic programming techniques can significantly simplify the code you write. One such technique is the ability to interact with database tables without having to directly reference them in your code. This approach can be particularly useful when you're working with multiple tables of similar structure, or when table names are only known at runtime. One common scenario is wanting to add an object to a database table using its name as a string. In this guide, we'll explore how to solve this particular problem with Entity Framework Core.
The Problem
You may find yourself in a situation where you want to add an object to a table in your database without explicitly referencing that table in your code. For example, instead of writing:

You might prefer a more dynamic approach, like this:

However, using dbContext.Find("Table1") directly like this doesn’t work since the Find method is not designed to take table names as strings. So, how can we achieve this functionality in a clean and efficient manner?
The Solution
The solution to this problem involves using a combination of reflection and Entity Framework Core. Here’s a step-by-step guide to dynamically insert records into a table using the name of the table as a string.
Step 1: Create a Generic Method
First, you can create a generic method inside your repository or service class that can perform the insertion. This method will accept the table name as a string, the object to insert, and the context instance:

Step 2: Utilize Reflection
You will need to ensure that you can access the correct DbSet based on the provided table name. You can use reflection to achieve this. Here’s an example code that makes use of it:

Step 3: Call the Method
Now that you have this method ready, you can call it by passing the name of the table and the entity you wish to insert. Here's an example call:

Conclusion
Using Entity Framework Core's reflection capabilities, you can dynamically add records to a database table, utilizing the table’s name as a string. This approach enhances the flexibility and maintainability of your code. It avoids hardcoding table names, which can be a hassle when dealing with multiple tables or when table names may change over time.
Implementing these kinds of dynamic methods can empower your data access layer, making it robust and adaptable for future modifications. This code not only serves the immediate need for dynamic table access but also showcases the capabilities of the C# language, helping you become a more versatile developer.
In summary, using Entity Framework Core along with reflection to insert entities dynamically can significantly streamline your development workflow and promote best practices in programming.
