本文介绍了连接字符串中的撇号（单引号）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在连接字符串中的’字符时遇到麻烦。实体框架引发异常：

I'm having a trouble with the ' character in a connection string. Entity Framework throws an exception saying:

初始化字符串的格式不符合从索引开始的规范

Format of the initialization string does not conform to specification starting at index

我尝试了建议的答案此处和

I tried the answers suggested here and here to no avail.

我也尝试使用 SqlConnectionStringBuilder 类构造它，并得到相同的异常结果。

I also tried constructing it with SqlConnectionStringBuilder class and got the same exception as a result.

有人可以帮我吗？

预先感谢。

编辑：

连接字符串确实位于web.config文件中，它看起来像这样：

The connectionstring is indeed in the web.config file and it looks like this:

<add name="TestEntities" connectionString="metadata=res://*/DAL.TestModel.csdl|res://*/DAL.TestModel.ssdl|res://*/DAL.TestModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.\testsource;initial catalog=testdb;User Id=testuser;Password=test'password;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

问题在于 Password = test'password 位。

我不能将其用双引号引起来，因为它已经被它们包围了。

我不能把它放在& -s之间，因为它也已经被它们包围了。

我不能将其用单引号引起来，因为单引号本身就是我要逃脱的内容。

I can't put it in double quotes because it's already surrounded by them.

I can't put it between &quot;-s because it's already surrounded by them too.

And I can't put it in single quotes because the single quote itself is what I'm trying to escape.

Password ='test&'password'不起作用。

推荐答案

我终于迷失了一个正确答案。看起来，您必须用单引号将值引起来，并另外复制内撇号以使其逃逸，如下所示：

I have finally stumbled upon a correct answer. It appears, you have to surround the value with single quotes and additionally duplicate the inner apostrophe in order to escape it, like this:

Password = 'test'password'

这是一个愚蠢的问题，浪费了很多时间。我希望它可以节省将来的时间。

This is such a dumb problem to waste this much time on. I hope it saves somebody time in the future.
