为程序设置sqlserver名称 [英] set sqlserver name for program

问题描述

我有组合框，其中显示服务器名称和sqlserver名称。例如：.\SQLExpress



sqlconnection是：

i have combobox where show server name and sqlserver name. for example : .\SQLExpress

sqlconnection is :

SqlConnection conn = new SqlConnection("Data Source='"+comboBox1.SelectedValue+"';AttachDbFilename=|DataDirectory|\\dbname.Mdf;Integrated Security=True;Connect Timeout=30;User Instance=True");

现在comboBox1.SelectedValue不适用于程序。用户如何选择动态servername和sqlserver名称来连接数据库（sqlserver数据库）？

plz help。

now comboBox1.SelectedValue is not work for program . how user select dynamic servername and sqlserver name for connect to database (sqlserver database) ?
plz help .

推荐答案

你好，



尝试 comboBox1.Text 而不是 comboBox1.SelectedValue ：

Hi,

Try comboBox1.Text instead of comboBox1.SelectedValue:

SqlConnection conn = new SqlConnection("Data Source='"+comboBox1.Text+"';AttachDbFilename=|DataDirectory|\\dbname.Mdf;Integrated Security=True;Connect Timeout=30;User Instance=True");

Hope这有帮助。
