Cannot convert string to Enum type I created [duplicate]
I have an enum:
开发者_运维问答public enum Color
{
Red,
Blue,
Green,
}
Now if I read those colors as literal strings from an XML file, how can I convert it to the enum type Color.
class TestClass
{
public Color testColor = Color.Red;
}
Now when setting that attribute by using a literal string like so, I get a very harsh warning from the compiler. :D Can't convert from string to Color.
Any help?
TestClass.testColor = collectionofstrings[23].ConvertToColor?????;
Is something like this what you're looking for?
TestClass.testColor = (Color)Enum.Parse(typeof(Color), collectionofstrings[23]);
Try:
TestClass.testColor = (Color)Enum.Parse(typeof(Color), collectionofstrings[23]);
See documentation about Enum
Edit: in .NET 4.0 you can use a more type-safe method (and also one that doesn't throw exceptions when parsing fails):
Color myColor;
if (Enum.TryParse(collectionofstring[23], out myColor))
{
// Do stuff with "myColor"
}
You need to use Enum.Parse to convert your string to the correct Color enum value:
TestClass.testColor = (Color)Enum.Parse(typeof(Color), collectionofstrings[23], true);
As everyone else has said:
TestClass.testColor = (Color) Enum.Parse(typeof(Color), collectionofstrings[23]);
If you're having an issue because the collectionofstrings
is a collection of objects, then try this:
TestClass.testColor = (Color) Enum.Parse(
typeof(Color),
collectionofstrings[23].ToString());
