asp.net SqlParameter关于Like的传参数无效问题

复制代码 代码如下:

String searchName ="Sam";
String strSql = "select * FROM Table1 where Name like '%@Name%' ";
SqlParameter[] parameters = {
new SqlParameter("@Name", searchName)
};

复制代码 代码如下:

String searchName ="Sam";
String strSql = "select * FROM Table1 where Name like @Name ";
searchName = "%"+searchName+"%"; //注意不用加单引号，传参到Sql语句中会自动添加
SqlParameter[] parameters = {
new SqlParameter("@Name", searchName)
};
