新手求助
SQL语句:select   *   from   EmployyInfo   where   EmployyId   =1 
 SqlCommand   command   =   new   SqlCommand( "select   *   from   EmployyInfo   where ' "+this.comboBox1.text+ " '= ' "+this.textBox1.Text+ " ' ",   MyCon);    
 当我在combobox1中输入    "EmployyId "      在this.textbox1.text中输入 "1 "时   我想检索   EmployyInfo表中EmployyId为1   的记录   这条语句不能实现. 
 要怎么写呢?谢谢
