ASP.NET获取MS SQL Server安装实例实现思路及代码

Server: <asp:DropDownList ID="DropDownListInstance" runat="server"></asp:DropDownList> 
 
然后在Page_Load事件写： 
 代码如下:

View Code 
protected void Page_Load(object sender, EventArgs e) 
{ 
DataTable dataTable = SqlDataSourceEnumerator.Instance.GetDataSources(); 
foreach (DataRow dr in dataTable.Rows) 
{ 
if (string.IsNullOrEmpty(dr["InstanceName"].ToString())) 
this.DropDownListInstance.Items.Add(string.Concat(dr["ServerName"])); 
else 
this.DropDownListInstance.Items.Add(string.Concat(dr["ServerName"], "\\", dr["InstanceName"])); 
} 
} 
 
运行结果，Insus.NET的手提电脑安装了SQL Server 2012和SQL Server 2008 R2，因此显示两个SQL Server实例。
