推荐答案
您的sql正在插入一个名为Table的表中。如果这是正确的，你的表真的被调用，那么解决方案是将表重命名为适当的类似用户。无论如何，当你使用关键词作为表或字段名称时，你需要将它们放在方括号中，这样SQL就知道你的字面意思是
Your sql is inserting into a table literally called Table. If that is right and your table is really called that then the solution is to rename the table to something appropriate like "User". Regardless, when you use key words as table or field names you need to put them in square brackets so SQL knows you mean them literally
string insert = "insert into [Table](username,email,password,country) values (@uname,@email,@pwd,@country)";
如果您的表未被称为Table，则只需使用正确的名称替换Table。
If your table isn't called Table then simply replace Table with the correct name.
