Additionally: Can I use an expression (for example an extension method

C#

TestEnum.Enum1.DoSomething()

public enum TestEnum: int
{
    Enum1 = 3,
    EnumZwei = 9
}

public static class MyExt
{
    public static TestEnum DoSomething(this TestEnum e)
    {
        return TestEnum.EnumZwei;

I hoped that I could use something like

C#

<CheckBox IsChecked="{Binding Obj[TestEnum.Enum1]}" ...

with some helper object providing an index operator. The first works, the second does not...

public static class MyExt
{
    public static string Parse(this string SomeString)
    {
        foreach (var enumVal in Enum.GetValues(typeof(TestEnum)))
        {
            string enumValAsString = String.Format("{0}.{1}", 
                enumVal.GetType().Name, enumVal);
            int enumValAsInt = (int)enumVal;
            if (SomeString.Contains(enumValAsString))
            {
                SomeString = SomeString.Replace(enumValAsString, enumValAsInt.ToString());
            }
        }
        return SomeString;
    }
}
// and an example on using that;
class Program
{    
    public static void Main (string[] args)
    {    
        string s = "{Binding Obj[TestEnum.Enum1]}";
        Console.WriteLine(s);
        Console.WriteLine(s.Parse());
    }
}

if you can't read my code, try converting it here[^]

The FileContent property gets a Stream object that points to a file to upload. Use this property to access the contents of the file as bytes. For example, you can use the Stream object that is returned by the FileContent property to read the contents of the file as bytes and store them in a byte array. Alternatively, you can use the FileBytes property to retrieve all the bytes in the file.
