Guid::ParseExact Method (String^, String^)

 

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)

public:
static Guid ParseExact(
	String^ input,
	String^ format
)

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".

Return Value

Type: System::Guid

A structure that contains the value that was parsed.

Exception Condition
ArgumentNullException

input or format is null.

FormatException

input is not in the format specified by format.

The ParseExact method requires the string to convert to be exactly in the format specified by the format parameter, after leading and trailing white-space characters are removed. 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(String^) 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 ParseExact method, which successfully parses only the string that conforms to the "B" format specifier.
