Guid.TryParse Method (String, Guid)
Converts the string representation of a GUID to the equivalent Guid structure.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- input
-
Type:
System.String
The GUID to convert.
- result
-
Type:
System.Guid
The structure that will contain the parsed value. If the method returns true, result contains a valid Guid. If the method returns false, result equals Guid.Empty.
This method is like the Parse method, except that instead of returning the parsed GUID, it returns false if input is null or not in a recognized format, and doesn't throw an exception. It trims any leading or trailing white space from input and converts strings in any of the five formats recognized by the ToString(String) and ToString(String, IFormatProvider)methods, as shown in the following table.
Specifier | Description | Format |
|---|---|---|
N | 32 digits | 00000000000000000000000000000000 |
D | 32 digits separated by hyphens | 00000000-0000-0000-0000-000000000000 |
B | 32 digits separated by hyphens, enclosed in braces | {00000000-0000-0000-0000-000000000000} |
P | 32 digits separated by hyphens, enclosed in parentheses | (00000000-0000-0000-0000-000000000000) |
X | Four hexadecimal values enclosed in braces, where the fourth value is a subset of eight hexadecimal values that is also enclosed in braces | {0x00000000,0x0000,0x0000,{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00}} |
The following example creates a new GUID, converts it to three separate string representations by calling the ToString(String) method with the "B", "D", and "X" format specifiers, and then calls the TryParse method to convert the strings back to Guid values.
