I'm generating a barcode value in a method.And I want to get this value according to the values in the foreach. How can I call the value of the method that returns the value.

public void GenerateBacode(string _barcodedata)
 {
    return _barcodedata
 };

What I have tried:

foreach(var _a in Clothes)
{
if( xx < 5)
{
     tshirt.Add(new Clothes()
    {
       Clothes_Color="Blue",
       Clothes_SaveType=1,
       Clothes_Barcode=GenerateBarcode();   //// This line is error generated barcode can not write value

     }
}

}

You have to match the signature of the method when you are calling it. Here:

you should define the return type of the method (string instead of void) as already stated in solution 1.
you defined the method as having a single string argument, but you do not provide any when you call it.

All these mistakes should generate errors in the IDE anyway, and you should not be able to compile because of them.
There also seems to be an issue with the naming: Clothes seems to represent a class and a collection of objects at the same time.
Maybe you need to get back to c#/OOP 101, and grasp these essential notions?

Solution 1

You're "returning" something from your method, which cannot be "void". Replace "void" with the "type" of the object you're returning.

necessarily return value. So how do I?

Your

GenerateBacode

method is void, thus can not return anything, at leas via return value. Give this method a return type which suite for your needs.

This probably a bad typo, but you define

GenerateBacode

however you call the

GenerateBarcode

method.

And a last one hint. You wrote "barcode can not write value", if I'm correct, then you can not assign value to left side of equal sign. Maybe that member is a readonly field or simply a "getter" property.

Solution 4

Change your method to

public string GenerateBacode(string _barcodedata)
{
return _barcodedata;
}
