 Public method | TryFromWellKnownText(System.String wellKnownText, out Crs crs) | Returns a Coordinate Reference System specified by Well-Known Text. The DatumShiftChoice will be Conservative if there is no explicit datum shift in the WKT. |
| Public method | TryFromWellKnownText(System.String wellKnownText, DatumShiftChoice datumShiftChoice, out Crs crs) | Returns a Coordinate Reference System specified by Well-Known Text, using a given DatumShiftChoice. |
TryFromWellKnownText(System.String wellKnownText, out Crs crs)
Returns a Coordinate Reference System specified by Well-Known Text. The DatumShiftChoice will be Conservative if there is no explicit datum shift in the WKT.Syntax
public static System.Boolean TryFromWellKnownText (
System.String wellKnownText,
out Crs crs
)Parameters
wellKnownText
Type: System.String
The Well-Known Text.
The Well-Known Text.
crs
Type: Crs
The resulting Coordinate Reference System. This is an output parameter, and it will only be valid if the return value is True.
The resulting Coordinate Reference System. This is an output parameter, and it will only be valid if the return value is True.
Return Value
Type: System.Boolean
In C# and C++ this method returns True if the Well-Known Text was successfully interpreted as Coordinate Reference System definition, and False otherwise. In Java and Python, the actual Coordinate Reference System is returned, or null (Java) or None (Python) if the text could not be interpreted.

Remarks
If the datum shift is not given explicitly in the WKT, a default datum shift for the geodetic datum will be chosen in the Conservative way, so the method can fail if Carmenta does not know any generally useful datum shift. Note that there is an overloaded variant that lets you specify the Lenient datum shift choice instead.
TryFromWellKnownText(System.String wellKnownText, DatumShiftChoice datumShiftChoice, out Crs crs)
Returns a Coordinate Reference System specified by Well-Known Text, using a given DatumShiftChoice.Syntax

datumShiftChoice
Type: DatumShiftChoice
Tells how the datum shift shall be chosen (Conservative or Lenient) if there is no explicit datum shift in the WKT.
