C# – How to scroll down in a textbox by code in C#

cscrolltextboxwinforms

I am using winforms, and I update a text box once in a while (showing messages).
however, when the text reaches the end of the box it produces scrollbars and I don't know how to scroll down to the bottom. The only thing I see is ScrollToCaret, but Caret is at the beginning of the text. What is the command to scroll?

You can do this by making use of a function called ScrollToCaret. You need to first set the caret position to the end of the text box, then you can scroll to it. Here's how to do it:

        //move the caret to the end of the text
        textBox.SelectionStart = textBox.TextLength;
        //scroll to the caret
        textBox.ScrollToCaret();

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);

C# – How to enumerate an enum

foreach (Suit suit in (Suit[]) Enum.GetValues(typeof(Suit)))
{
}

Note: The cast to (Suit[]) is not strictly necessary, but it does make the code 0.5 ns faster.
