No. You’re not likely to notice any performance difference unless you are looping billions of times.

Typically with C# you don’t want to waste much time micro-optimizing. In other words, just write the code you want and don’t worry too much about performance. Then once you have the code working the way you want it, if you notice any performance issues, use a profiler to identify trouble spots, then optimize the slow sections of code as necessary.

1) I would like to chain constructors as shown below,
because in this way all the initialization logic is in just one place

private Test( bool a, int b )
: this( a, b, “”, -1 )

{
}

public Test( bool a, int b, string c )
: this( a, b, c, -1 )
{
}

public Test( bool a, int b, float d )
: this( a, b, “”, d )
{
}
public Test( bool a, int b, string c, float d )
{
this.m_A = a;
this.m_B = b;
this.m_C = c;
this.m_D = d;

}

2) I would like only the last constructor (with 4 parameters) to look like below:

Is it a problem for a performance point of view ?

public Test( bool a, int b, string c, float d )
{
Initialize(a, b, c, d);
}

public Initialize( bool a, int b, string c, float d )
{
this.m_A = a;
this.m_B = b;
this.m_C = c;
this.m_D = d;

}

Allow me one question please:

- Once a Test object is created, I feel there’s a need for a method like this:
Initialize(a,b, c)

Test test = new Test(true,2,”3″);

test.Initialize(false,8,”9″);
test.Initialize(true,10,”11″);

How would you write the Initialize method in order to avoid copy paste code from the constructor ??

public Initialize( bool a, int b, string c )
{
this.m_A = a;
this.m_B = b;
this.m_C = c;
}
