在 appsettings.json 中的连接字符串中转义双引号

Question

在我的 .NET 5 Web 应用程序中，我的 appsettings.json 连接字符串如下：

"ConnectionStrings": {
    "Default": "Server=.; Database=XKCDPublicDb; user id=nitin;password=\"XKCDDUMMY}Xb\"f~\""
}

如您所见，密码包含双引号，因此我使用\\"转义，但仍然出现以下错误：

Format of the initialization string does not conform to specification starting at index 49.
ArgumentException: Format of the initialization string does not conform to specification starting at index 49.

用单引号'包围密码，它起作用了

"ConnectionStrings": {
    "Default": "Server=.; Database=XKCDPublicDb; user id=nitin;password='XKCDDUMMY}Xb\"f~'"
}
