Returns a string representation of the value of this instance of the Guid class, according to the provided format specifier and culture-specific format information.
Syntax
Parameters
- format
- provider
Returns
The value of this Guid, represented as a series of lowercase hexadecimal digits in the specified format.
Remarks
The provider parameter is reserved for future use and does not contribute to the execution of this method. You can pass null in the method call.
The following table shows the accepted format specifiers for the format parameter. "0" represents a digit; hyphens ("-"), braces ("{", "}"), and parentheses ("(", ")") appear as shown.
| 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 hexadecimal digits a through f are lowercase in the returned string. To convert them to uppercase, call the string.ToUpper method on the returned string.
Because the provider parameter is ignored, you cannot use it to provide a custom formatting solution. To represent a Guid value as a string in a format that isn't supported by the standard GUID format strings, call the string.Format(IFormatProvider, string, Object[]) method with a provider object that implements both the ICustomFormatter and IFormatProvider interfaces. For more information, see the "Custom Formatting with ICustomFormatter" section in the Formatting Types article.
