您的插入查询中的列名不能包含空格-例如“邮件ID”或“手机号码”。

如果您的表中确实有这样的列（确实是坏设计选择，应该避免！），那么必须将这些列名称括在方括号中-像这样：

string query = 
    "INSERT INTO [Table] (Name, [Mail ID], Password, Gender, Address, 
                          [Select District], Pincode, [Mobile Number], Qualification, 
                          [Adhar Number], [ID Proof], [ID Proof Number],
                          [Select Nearest Police Station]) 
     VALUES (@name, @mailid, @password, @gender, @address, 
             @selectdistrict, @pincode, @mobilenumber, @qualification, 
             @adharnumber, @idproof, @idproofnumber, @selectnearestpolicestation)";

另外，使用T-SQL保留关键字Table作为表或列名称是另一个非常糟糕的命名选择-尝试避免这种情况，这只是麻烦和头痛的秘诀-而且选择不当名称也是如此，因为它实际上并不传达表包含的数据类型。
