Method to assign to desired property within loop (lambda?)

Lets say you have a vector2 array and you want to loop through them all to change only the x or y values. How would you do this?

For example (this doesnt work)..

Code (CSharp):

1.     void MoveUVs(Action<Vector2> delegateAction, int targetSpace)
2.     {
3.         for(int i = 0; i < uvs.Length; i++)
4.         {
5.             delegateAction(uvs[i]) += targetSpace;
6.         }
7.     }

An action returns void, and using a func doesnt seem to work either. The func could return a float, but that float is not part of the original vector anymore.
I want to basically be able to do this...

Code (CSharp):

1. //move x values in the vector
2. MoveUVs((v) => v.x, 5);
3.  
4. //move y values in the vector
5. MoveUVs((v) => v.y, 5);

Right now I can do something like this

Code (CSharp):

1. MoveUVs((v, i, t) => v[i].x += t, targetSpace);
2.  
3. void MoveUVs(Action<Vector2[], int, int> delegateAction, int targetSpace)
4. {
5.     for(int i = 0; i < uvs.Length; i++)
6.     {
7.             delegateAction(uvs, i, targetSpace);
8.     }
9. }

But I dont like that.

 

Responding from my iPad, so sorry if the answer is rather incomplete.
I would use masks for selecting the component to affect.

Like so:

class VectorMask
{
public const Vector2 x = new Vector2(1f, 0f);
public const Vector2 y = new Vector2(0f, 1f);
public const Vector2 xy = new Vector2(1f, 1f);
}

MoveUVs(VectorMask.x, 5f);
MoveUVs(VectorMask.xy, 2f);

void MoveUVs(Vector2 mask, float targetSpace)
{
Vector2 offset = Vector2.Scale(new Vector2(targetSpace, targetSpace), mask);

// Loop through all uvs and just add offset to each.
}

Since I use Vector2.Scale(), any component which has 0f as value in the mask will be zeroed out from the offset and therefore wont affect the uvs.

 

Following KISS principle:

Code (csharp):

1.  
2. Vector2[] Vectors;
3.  
4. Vectors
5.     .ToList()
6.     .ForEach(v => v += new Vector2(5, 0));
7.  

 

I'm more interested in being able to grab any property value I want and being able to pass it and assign to it directly within another method. I guess this isn't really possible? The property will lose its reference.

Your answers are more so workarounds such as the answer I gave.
