Guid.TryParseExact Method

Updated: August 2011

Converts the string representation of a GUID to the equivalent Guid structure, provided that the string is in the specified format.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

static member TryParseExact : 
        input:string * 
        format:string * 
        result:Guid byref -> bool 

Parameters

input
Type: System.String
The GUID to convert.
format
Type: System.String
One of the following specifiers that indicates the exact format to use when interpreting input: "N", "D", "B", "P", or "X".
result
Type: System.Guid%
The structure that will contain the parsed value.

Return Value

Type: System.Boolean
true if the parse operation was successful; otherwise, false.

This method returns false if input is a null reference (Nothing in Visual Basic) or not in a recognized format, and does not throw an exception.

The following table shows the accepted format specifiers for the format parameter. "0" represents a digit; hyphens ("-"), braces ("{", "}"), and parentheses ("(", ")") appear as shown.

Specifier

Format of the input parameter

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 calls the ToString method with each of the supported format specifiers to generate an array of strings that represent a single GUID. These are then passed to the TryParseExact method, which successfully parses the string that conforms to the "B" format specifier.

No code example is currently available or this language may not be supported.
