Is it possible to to define a string from a variable where the string does NOT have quotations. Example:
public class aclass
{
public string athing;
}
public void example(string thing)
{
aclass thing = new aclass();
}
The string thing can't be put into aclass thing = new aclass(); normaly.
Is there anyway to do it?
You need a constructor
void Main()
{
CreateExampleObject("testing");
}
public class Example
{
// This is a constructor that requires a string as an argument
public Example(string text)
{
this.Text = text;
}
public string Text { get; set; }
}
public void CreateExampleObject(string text)
{
Example example = new Example(text);
Console.WriteLine(example.Text);
}
You can do it this using many way but generally standard way is using constructor please refer this link for better understanding.
C# : assign data to properties via constructor vs. instantiating
You have to ways of setting fields/property value of an object.
First is to do it through the constructor, as mentioned in other answer.
Second can be implmeneted in various ways:
Expose public property making field privte:
public class aclass
{
private string _athing;
public string Athing
{
get { return _athing; }
set { _athing = value; }
}
}
public void example(string thing)
{
aclass aclass = new aclass();
aclass.Athing = thing;
}
Or even shorter, you could use property:
public class aclass
{
public string Athing {get; set; }
}
Using your implementation, you make your field public, so you can set it easily:
public void example(string thing)
{
aclass aclass = new aclass();
aclass.athing = thing;
}
But it doesn't comply with OOP encapsulation principle.
stringas argument, e.g.public aclass(string value) { athing = value; }before usingaclass thing = new aclass("somestring");.
