将数据绑定到数据列表时出现此错误asp.net字符文字中的字符过多

I'm getting this error while binding data to data list too many characters in character literal asp.net

推荐答案

字符文字中的字符过多"是由于其中的字符字面过多而引起的.

"too many characters in character literal" is caused by having a char-literal with too many characters in it.

您可能混淆了'-字符和"-字符.

You have probably mixed up the '-character and the "-character.

错误可能出在您的"android.aspx.cs"文件中，而不是您提供的.aspx文件中.

The error probably lies in your "android.aspx.cs"-file rather than the .aspx-file that you have provided.

您能提供相应的代码吗?

Could you provide the code for that as well?

好吧，您的问题就在这里:

Well, your problems are right here:

<%# Bind('ModelID') %>

用双引号替换单引号，您会变得很高兴！

Replace your single-quotes with double-quotes and you will be golden!

<%# Bind("ModelID") %>

您的所有评估/绑定都适用

Same goes for all your Evals/Binds
