推荐答案

要使字段能够存储 unicode 字符，您必须使用类型 nvarchar (或其他类似 ntext, nchar).

For the field to be able to store unicode characters, you have to use the type nvarchar (or other similar like ntext, nchar).

要在数据库中插入 unicode 字符，您必须使用 nvarchar/SqlDbType.NVarChar 等参数类型将文本作为 unicode 发送.

To insert the unicode characters in the database you have to send the text as unicode by using a parameter type like nvarchar / SqlDbType.NVarChar.

(为了完整起见:如果您是动态创建 SQL(违反常见建议)，则在字符串文字前放置一个 N 以使其成为 unicode.例如:insert into table (name) values (N'Pavan').)

(For completeness: if you are creating SQL dynamically (against common advice), you put an N before a string literal to make it unicode. For example: insert into table (name) values (N'Pavan').)
