如何将字符串转换为uniqueidentifier？

Question

I want to insert a string into a table as a uniqueidentifier type. But when I insert it to the database, it throws an error. How can i convert a string to a uniqueidentifier ?

Answer 1

You can try:

new Guid("string to convert");

But the string will need to be in Guid format already.

Answer 2

在.Net 4中，有一个Guid.TryParse(string, out Guid) ，它在成功时返回bool 。

Answer 3

This is a safe way to attempt parsing a string into a Guid . In my example, input is a string variable from the user:

var myGuid = new Guid();
if (Guid.TryParse(input, out myGuid)) {
    // Parsed OK
}

Answer 4

use one of these:

Guid.TryParse

or

Guid.TryParseExact
