How Can I Execute Code from a File in My WPF C# Application?

Dynamic Code Execution in WPF C# Applications

This guide demonstrates how to execute code from an external text file within your WPF C# application using a button click. The code file should reside in your application's execution directory. This dynamic execution is achieved through these steps:

1. File Input: Read the code from the text file into a string variable.

2. CSharpCodeProvider: Instantiate a CSharpCodeProvider object to handle code compilation.

3. Compiler Parameters: Configure compiler parameters. Set GenerateInMemory to true (compile in memory) and GenerateExecutable to false (avoid creating an executable).

4. Compilation: Use the CSharpCodeProvider to compile the code string using the specified parameters.

5. Error Handling: Check the Errors property of the CompilerResults object for compilation errors and handle them appropriately.

6. Instance Creation: Upon successful compilation, create an instance of the compiled class using CreateInstance.

7. Method Invocation: Use reflection to invoke the desired method within the compiled class (e.g., SayHello()).

This method allows for flexible code updates and modifications without requiring a full application recompile. Remember to handle potential security risks associated with executing arbitrary code.
