Error in constructor //

[vedro-compota]

Hi.
Could you tell me - what is wrong here -

public class MAP 
    {
        public string MAP(string FilePath) 
       {
           FileStream fs; 
           try { fs = new FileStream(FilePath, FileMode.Open); }  
           catch (FileNotFoundException exp) { return exp.Message; }
           catch  { return "Не удаётся открыть файл"; }
           return "all right!";
           
           
       }
        
    }

compiler "says" that -

Error 1 'MAP': member names cannot be the same as their enclosing type

but,as I know - that constructor name should be the same as the name of the class....
thanks in advance )

YOu names the class as "MAP" and the same name is the method in it.
The constructor can be the only method which can have the same name as the class.

Example:

class ExampleClass
{
    public ExampleClass()
    {
         //constructor of class ExampleClass!
    }

    private void Method1()
    {        
        //method in ExampleClass
    }
   
    private string Method2()   
    {
        method in ExampeClass
        string a = null;
        //some code in here
        return a;
    }
}

remember... no method or even handler can have the same name as the class name (except the class`s constructor).

If you wanted to have some code in the constructor, you can not declare the return type.
You can see the example of constructor declarations here.
Hope this helps,

I didn't know about it.....thank you Mitja Bonca)

Ah ... one more question - Ah ... one more question -Can I transfer the values to the constructor? like this -

public ExampleClass(int a)

[jugosoft]

You can, like you pass values to for example SqlConnection constructor.

[ddanbe]

Of course you can, you can even have things like

public ExampleClass(int a, string b, double c)

See also the link Mitja gave you.

thank you very much))

please tell me - what's wrong with this constructor-

public class [B]DinArray[/B] // 1 - int ; 2 - масссив городов -City
    {
        public void [B]DinArray[/B](int size, int type)
        {
            switch (type) 
            {
                case 1: 
                    this.ArrayOfInt = new int[size];
                    this.Length = size;
                break;
                case 2:
                this.ArrayOfCities = new CITY[size];
                this.Length = size;
                break;

            }
         }
     }

error -

Error 1 'DinArray': member names cannot be the same as their enclosing type

[CloneXpert]

a constructor shouldn't have a return type (in your case it's void, this is why you are getting that error message), instead write it like this:

public DinArray(int size, int type)
        {
...

thank you, CloneXpert ))
