How is the use of GUID in C#?

In C#, you can utilize the following method to use a GUID (Globally Unique Identifier):

1. Generate a new unique identifier.

Guid guid = Guid.NewGuid();

1. Convert a string representation of a unique identifier to a GUID data type.
2. Check if the input can be parsed as a GUID.
3. Create a new GUID from a string.
4. Checking if a string can be converted to a GUID.

string guidString = "e54a8ac7-8f62-4d46-9ff9-4559d8e7ac91";
Guid guid = Guid.Parse(guidString);

// 或者使用TryParse方法
bool success = Guid.TryParse(guidString, out Guid guid);
if (success)
{
    // 转换成功，可以使用guid变量
}

1. Convert to a string

Guid guid = Guid.NewGuid();
string guidString = guid.ToString();

1. Is the same as()
2. Please rephrase the following sentence in your own words.

Guid guid1 = Guid.NewGuid();
Guid guid2 = Guid.NewGuid();

bool areEqual = guid1.Equals(guid2);
bool areEqual = (guid1 == guid2);

These are some common methods and operations using GUID. Other methods and properties may also be utilized to perform additional operations as needed, such as obtaining the byte array representation of the GUID or converting the GUID to other data types.
