Answer 1

使用此First Name，例如[First Name]和其他列。

如果列名中有空格，则应始终使用[]。你也应该避免列名中的空格。

所以你的代码变成了

string insertquerry = "insert into Donor([First Name], [Last Name], 
    [Cell number], Email, CNIC, City, Address, Blood Group, Gender, 
    Password) values (@firstname, @lastname, @cell, @email, @cnic, @city, 
     @address, @blood, @sex, @password)";

在我的数据库中插入数据但是抛出异常
