如何列出本地计算机上安装的SQL Server实例？ （仅限本地）

我想知道是否有一种方法可以列出本地计算机上安装的SQL Server实例。

SqlDataSourceEnumerator和EnumAvailableSqlServers没有这个技巧，因为我不需要通过本地网络的实例。

Answer 1

您可以使用localOnly = True调用EnumAvailableSQlServers

 public static DataTable EnumAvailableSqlServers(bool localOnly) 

请参阅EnumAvailableSqlServers的MSDN文档

Answer 2

MS建议不直接访问Windows注册表，因为它们可以更改密钥/路径。 但我同意SmoApplication.EnumAvailableSqlServers（）和SqlDataSourceEnumerator.Instance无法在64位平台上提供实例。

从Windows注册表获取数据，请记住x86和x64平台之间注册表访问的差异。 64位版本的Windows将数据存储在系统注册表的不同部分，并将它们组合到视图中。 所以使用RegistryView是必不可少的。

 using Microsoft.Win32; RegistryView registryView = Environment.Is64BitOperatingSystem ? RegistryView.Registry64 : RegistryView.Registry32; using (RegistryKey hklm = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, registryView)) { RegistryKey instanceKey = hklm.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL", false); if (instanceKey != null) { foreach (var instanceName in instanceKey.GetValueNames()) { Console.WriteLine(Environment.MachineName + @"\" + instanceName); } } } 

如果您在64位操作系统上寻找32位实例（非常奇怪，但可能），您需要查看：

 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server 

Answer 3

 SqlDataSourceEnumerator instance = SqlDataSourceEnumerator.Instance; System.Data.DataTable table = instance.GetDataSources(); foreach (System.Data.DataRow row in table.Rows) { if (row["ServerName"] != DBNull.Value && Environment.MachineName.Equals(row["ServerName"].ToString())) { string item = string.Empty; item = row["ServerName"].ToString(); if(row["InstanceName"] != DBNull.Value || !string.IsNullOrEmpty(Convert.ToString(row["InstanceName"]).Trim())) { item += @"\" + Convert.ToString(row["InstanceName"]).Trim(); } listview1.Items.Add(item); } } 

Answer 4

您可以使用注册表在本地系统中获取SQL Server实例名称

 private void LoadRegKey() { RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names"); foreach (string sk in key.GetSubKeyNames()) { RegistryKey rkey = key.OpenSubKey(sk); foreach (string s in rkey.GetValueNames()) { MessageBox.Show("Sql instance name:"+s); } } }

结合几种方法：
