【问题描述】：

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=\"XKCDDUMMYXb\"f~\""

你可以看到密码包含双引号，所以我使用\" 转义但我仍然收到以下错误：

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.

【问题讨论】：

尝试将双引号替换为" 必须使用 .Net Framework 连接字符串来转义特殊的 XML 字符。

@phuzi 这是一个 JSON 字符串，而不是 XML

这能回答你的问题吗？ Escape quote in web.config connection string

【参考方案1】：

用单引号 ' 将密码括起来，它起作用了

"ConnectionStrings": 
    "Default": "Server=.; Database=XKCDPublicDb; user id=nitin;password='XKCDDUMMYXb\"f~'"
