C# – How to cancel the execution of a method

c++

Consider i execute a method 'Method1' in C#.
Once the execution goes into the method i check few condition and if any of them is false, then the execution of Method1 should be stopped. how can i do this, i.e can the execution of a method when certain conditions are met.?

but my code is something like this,

int Method1()
{
    switch(exp)
    {
        case 1:
        if(condition)
            //do the following. **
        else
            //Stop executing the method.**
        break;
        case2:
        ...
    }
}

Best Solution

Use the return statement.

if(!condition1) return;
if(!condition2) return;

// body...

C# – the difference between String and string in C#

string is an alias in C# for System.String.
So technically, there is no difference. It's like int vs. System.Int32.

As far as guidelines, it's generally recommended to use string any time you're referring to an object.

e.g.

string place = "world";

Likewise, I think it's generally recommended to use String if you need to refer specifically to the class.

e.g.

string greet = String.Format("Hello {0}!", place);

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.

C# – How to cast int to enum

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);
