## Remarks
You can compare a GUID with the value of the <xref:System.Guid.Empty?displayProperty=nameWithType> field to determine whether a GUID is non-zero. The following example uses the <xref:System.Guid.op_Equality%2A> operator to compare two GUID values with <xref:System.Guid.Empty?displayProperty=nameWithType> to determine whether they consist exclusively of zeros.

Use the <xref:System.Guid.TryParse%2A> method to catch any unsuccessful parse operations without having to handle an exception.



## Examples
The following example creates a new GUID, converts it to three separate string representations by calling the <xref:System.Guid.ToString%28System.String%29> method with the "B", "D", and "X" format specifiers, and then calls the <xref:System.Guid.Parse%2A> method to convert the strings back to <xref:System.Guid> values.

## Examples
The following example calls the <xref:System.Guid.ToString%28System.String%29> 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 <xref:System.Guid.ParseExact%2A> method, which successfully parses only the string that conforms to the "B" format specifier.

The following example calls the <xref:System.Guid.NewGuid%2A> method to create a <xref:System.Guid> value, and then calls the <xref:System.Guid.ToByteArray%2A> method to represent the <xref:System.Guid> value as a byte array. It then displays both values to the console.
