我在 asp.net 上运行一个简单的应用程序，它从各个页面上的文本框中获取输入，然后在最后一页上通过适配器使用插入方法。当我对文本框使用像 hjihi 这样的虚拟输入时，并没有出现异常。但是，当我对字段使用正确的输入时，我会得到整页的可怕错误。搜索了它，但没有得到正确的答案。

Server Error in '/Job Portal10' Application.

描述：An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

异常详细信息：System.Data.SqlClient.SqlException：字符串或二进制数据将被截断。

此错误表明您正在尝试插入一些比指定列类型更长/更大的数据。一个简单的例子：你已经指定了一个类型为 varchar(200) 的列，但是你试图插入一个长度为 500 的字符串。

为了防止这样的异常，我建议对输入的数据实施某种客户端（当然是服务器端）验证。
