"servser=.;User id=sa;pwd="
加一个database="...";
他默认的库是master.你AM_admin是在master库中么
string yzConnStr="servser=.;User id=sa;pwd=";
好象不用.吧直接用(local)或者是IP就好了
string yzConnStr="servser=(local);User id=sa;pwd=";
servser=.;User id=sa;pwd="
加一个database="...";
string yzConnStr="servser=.;User id=sa;pwd= database=AM_admin";另外你的代码有问题你可以把他写到web.config中去 然后这样写
string settings = Convert.ToString(ConfigurationManager.ConnectionStrings["testConnectionString"]);
SqlConnection myconn = new SqlConnection(settings);
