- Source: [GitHub](https://github.com/CommunityToolkit/Aspire/blob/d479e13473b1d29d06b974f144a0049289a3cb5c/src/CommunityToolkit.Aspire.Logto.Client/LogtoConnectionStringHelper.cs#L26-L54)

Retrieves the endpoint value from a given connection string. If the connection string is a valid URI, the method returns the URI as a string. If the connection string is in a key-value pair format, it extracts the value of the "Endpoint" key if present and validates it as a URI.

```csharp
public static class LogtoConnectionStringHelper
{
    public static string? GetEndpointFromConnectionString(
        string? connectionString)
    {
        // ...
    }
}
```

## Parameters

- `connectionString` (`string?`)
  The connection string to parse for an endpoint.

## Returns

`string?` -- A string representation of the endpoint if found and valid; otherwise, null if the connection string is null, empty, or does not contain a valid endpoint.
