ADO.NET的一个问题,请高手指点,急!!!!!!!!!!!!
string   sql   =   null;
Conn.Open();
adminUser   =   "tianya ";
pwd   =   "123456 "
sql   =   "insert   into   YX_Manage   (YX_AdminUser,YX_Pwd)   values   (@YX_AdminUser,@YX_Pwd) ";
SqlCommand   Comm   =   new   SqlCommand(sql,   Conn);
Comm.Parameters.Add(new   SqlParameter( "@YX_AminUser ",   SqlDbType.VarChar,   50));
Comm.Parameters[ "@YX_AminUser "].Value   =   adminUser;
Comm.Parameters.Add(new   SqlParameter( "@YX_Pwd ",SqlDbType.VarChar,   50));
Comm.Parameters[ "@YX_Pwd "].Value   =   pwd;
Comm.ExecuteNonQuery();
Conn.Close();
程序执行出错,必须声明变量   '@YX_AdminUser '。  
请问到底是怎么回事啊!


------解决方案--------------------
@YX_AdminUser

@YX_AminUser 不一样哦
