[suners]

//调用卡信息
private void button1_Click(object sender, EventArgs e)
{


//localhost.Service ws = new localhost.Service();

WebReference.BalanceWebService ws = new WebReference.BalanceWebService();
string cardNo;
cardNo = ws.GetSecurityInfo("卡号").ToString();

tbid.Text = cardNo;


string password;
password = ws.GetSecurityInfo("密码").ToString();

tbpwd.Text = password;

string name;
name = ws.GetSecurityInfo("用户名").ToString();

this.tbmanager.Text = name;

string balance;
balance = ws.GetSecurityInfo("金款").ToString();

this.tbmoney.Text = balance;


//this.tbjqid.Text =IP ;

//this.tbyyid.Text = dcID;

}
在调用卡信息的时候不能调出。。。。调出的是其他信息。。。。
