推荐答案

对不起，但我很困惑.我们应该猜测是什么问题吗?

I''m sorry, but I am confused. Are we supposed to guess at what the problem is?

写道:​​

请告诉我什么是以下代码中的错误

please inform me what is the wrong in the below coding

1-您选择的主题很愚蠢.每个人都想要他们的问题的答案

2-

1 - your chosen subject is idiotic. EVERYONE wants an answer for their question

2 -

写道:​​

button1_Click

button1_Click

您似乎试图通过不给变量一个通俗易懂的名称来使代码不可读

3-

You seem to be trying to make your code unreadable, by not giving your variables sensible names

3 -

写道:​​

字符串conn =("INSERT INTO Categories(categoryName，description)" +"VALUES(""+ textName.Text +"' '，''"+ textadd.Text +"''));

string conn =( "INSERT INTO categories(categoryName,description)" + "VALUES('' " + textName.Text + "'',''" + textadd.Text + "'')");

您似乎对SQL注入一无所知，因此您正在编写一个带有数据库的系统，任何人都可以删除它.

4-您发布模糊的问题，几乎就像您不想回答一样.是什么让您感到此代码不起作用?您期望它做什么?它有什么作用 ?您会得到什么错误消息(如果有)，并由什么行生成?

请编辑您的帖子，并尝试根据我们需要了解的知识来尝试为您提供帮助.

You seem to know nothing about SQL injection, so you''re writing a system with a database that anyone can erase if they want to.

4 - you post vague questions, almost as if you don''t want an answer. What makes you feel this code is not working ? What do you expect it to do ? What does it do ? What error message, if any, do you get, and what line generates it ?

Please edit your post and try to think in terms of what we need to know in order to try to help you.
