C# 字符串或二进制数据将被截断。声明已终止。上载配置文件时
我正在尝试使用asp.net配置文件功能来存储用户信息。我在配置文件属性中有一个图像 我使用的是Visual Studio中asp.net提供的默认配置文件提供程序 下面是web.config中属性的定义C# 字符串或二进制数据将被截断。声明已终止。上载配置文件时,c#,asp.net,image,visual-studio-2013,profile,C#,Asp.net,Image,Visual Studio 2013,Profile,我正在尝试使用asp.net配置文件功能来存储用户信息。我在配置文件属性中有一个图像 我使用的是Visual Studio中asp.net提供的默认配置文件提供程序 下面是web.config中属性的定义 <properties> <add name="FirstName"/> <add name="MiddleName"/> <add name="LastName"/> <add name="Profil

检查要将数据插入的数据库列。为数据定义的长度小于要插入的长度
例如,如果您尝试向定义为Firstname Varchar(50)的列插入一个值,并且该值的长度超过50,则这将产生与您提到的相同的异常。问题的解决方案可能来自SQL Server的结构。
我建议您将SQL表中图像字段的类型从
binary
或任何字段更改为image
首先,您不应将图像数据类型与ntext一起使用,并且文本数据类型将在Microsoft SQL Server的未来版本中删除。如果你必须用它,那就好了。图像数据类型具有从0到2^31-1(2147483647)字节的可变长度二进制数据。所以它确实有一个限制。因为这个错误是针对一个34kb的文件而来的,不应该是这样的。我不会使用图像数据类型。但我也尝试过使用VarBinary(MAX),但它给出了相同的异常…发布更新数据库的代码。错误来自那里。我不会更新它。正如我提到的,我正在使用asp.net的配置文件功能。。。类Http.Context.Current.Profile有自己的更新函数,我没有修改过。那就是我没有超载。我应该这么做吗?你有没有试过不带个人资料图像。可能是另一列引发了异常。尝试先更新FirstName,然后逐个添加其他列。查看引发错误的内容并检查该错误的列定义。
