C# SQL Server数据库连接
【实例源码】朋友们好，该功能在测试中突然发现，通过Windows身份验证时，服务器IP与数据库值为空的时候，测试连接也会提示连接成功，这个BUG请大家给予帮助，谢谢！using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Data;using System.Data.SqlClient;namespace ConData{ public partial class ConnectionData : Form { public ConnectionData() { InitializeComponent(); } private void btnSQLOK_Click(object sender, EventArgs e) { string strcon = string.Format("server={0};database={1};uid={2};pwd={3};", this.txtIP.Text.Trim(), txtDataBase.Text.Trim(), txtUser.Text.Trim(), txtPwd.Text.Trim()); try { using (SqlConnection con = new SqlConnection(strcon)) { con.Open(); MessageBox.Show("测试成功！"); con.Close(); } } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void btnWindowsOK_Click(object sender, EventArgs e) { string strCon = string.Format("server={0};database={1};Trusted_Connection=SSPI", txtWindowsIP.Text.Trim(), txtWindowsDB.Text.Trim()); try { using (SqlConnection con = new SqlConnection(strCon)) { con.Open(); MessageBox.Show("测试成功！"); con.Close(); } } catch (Exception ex) { MessageBox.Show(ex.Message); } } }}
