Names Associated with a RegionInfo Object
While there is more than one names that can be used to construct a RegionInfo object, once it is created, there is a single name associated with it. This contrasts with the more complicated situation for CultureInfo objects, which is explained at Names Associated with a CultureInfo Object. .
Constructing a RegionInfo object and accessing its name
First, let us consider three examples in which System.Globalization.RegionInfo.#ctor(System.String) is used to construct a RegionInfo object. In .Net Framework version 1.0, this is very straightforward. For example, you would specify:
"US" for United States
"DE" for Germany
You cannot specify a custom culture.
In .Net Framework version 2.0, strings like "US" and "DE" continue to work in this context, but another approach is also introduced. You could specify a culture name to construct a RegionInfo object; only the region portion is relevant:
"en-US" (English - United States) for United States
"de-DE" (German - Germany) for Germany
This works similarly for a custom culture. For example, if "fj-FJ" is a defined custom culture, you could use that.
Let's look at the values each of these objects will return for RegionInfo.ToString and RegionInfo.Name:
| Method | en-US | De-DE | Custom Culture |
|---|---|---|---|
(region passed to constructor) |
US |
DE |
(N/A) |
(culture passed to constructor, introduced in .Net Framework version 2.0) |
en-US |
De-DE |
fj-FJ |
RegionInfo.ToString() |
US |
DE |
FJ |
RegionInfo.Name |
US |
DE |
FJ |
In short, the region name will be the same regardless of how it is constructed.
In addition, each region has a DisplayName, an EnglishName, a NativeName, a ThreeLetterISORegionName, a ThreeLetterWindowsRegionName, and a TwoLetterISORegionName. All of these are also independent of the method of construction.
Constructing a RegionInfo object by ID
The situation is essentially the same if you construct a RegionInfo object with System.Globalization.RegionInfo.#ctor(System.Int32), and specify a culture identifier. In this case, the culture values passed to the constructor are, respectively:
0x0409 for English - United States
0x0407 for German-Germany
0x0c00 for custom culture "fj-FJ". This will work only if "fj-FJ" is the current default user culture.
These objects will return the exact same names as in the previous example:
| Method | en-US | De-DE | Custom Culture |
|---|---|---|---|
(culture identifier passed to constructor) |
0x0409 |
0x0407 |
0x0c00 |
RegionInfo.ToString() |
US |
DE |
FJ |
RegionInfo.Name |
US |
DE |
FJ |
In short, these and all other names - DisplayName, EnglishName, etc. - will be independent of the method of construction.
