❔ Getting property from object based on input

Is it possible to create a function that would look something like this? Here I already have the object and I know for sure that the property actually exists. I'm quite new to C#, so I don't know if this is actually possible

private void(string propertyName)
{
   Console.WriteLine(myObject.propertyName.toString());
}

private void(string propertyName)
{
   Console.WriteLine(myObject.propertyName.toString());
}

yes, but why do you want this? You're likely just looking for a dictionary

The object is pulled from a database and I need to sometimes update things of it I don't want to make a function for every seperate part Right now I have like 4 different functions to update a single property, for example:

public void changeA(string newA)
{
    myObject.A = newA
}

public void changeA(string newA)
{
    myObject.A = newA
}

What does myObject look like

dond~OP•14mo ago

Some different values, so something like this:

public class myObject
{
public string Name{ get; set; }


public string Password{ get; set; }


public int IntProperty{ get; set; }


public double DoubleProperty { get; set; }
}

public class myObject
{
public string Name{ get; set; }


public string Password{ get; set; }


public int IntProperty{ get; set; }


public double DoubleProperty { get; set; }
}

There are no other objects in there

Firstly, properties, methods and types in C# should be PascalCase

dond~OP•14mo ago

Oh yea, they are, I just made a wrong example There's quite a lot of them so I didn't copy paste all of them

fair

dond~OP•14mo ago

There that is better

So if I'm understanding correctly, you're receiving a string from the database and you want to set all these properties to their corresponding values?

dond~OP•14mo ago

Well upon pressing a button, I want to change a value And I want to be able to pass the property that I want to change as well as the new value I have like 10 buttons that all change different values and instead of creating 10 different functions, I was wondering if it possible to combine that into one function So function should look something like this:

private void changeProperty(string property, T value)
{
   myObject.property = value
}

private void changeProperty(string property, T value)
{
   myObject.property = value
}

And then T is the type, because I have different types of properties within my object

You can do this using reflection, but that's 1) very slow, and 2) not type-safe You'd have to pass object to ChangeProperty method instead of a specific type

dond~OP•14mo ago

Hmm okay, thanks. Would it be faster if I make a seperate method per type of value? So like changePropertyString(string property, string value) changePropertyInt(string property, int value Etc.

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
