如何获取SQL Server数据库连接字符串的某些部分

有的时候需要获取SQL Server数据库连接字符串的某些部分。用正则表达式可能有点麻烦。

其实有一个比较简单的方法--使用SqlConnectionStringBuilder。

var builder = new SqlConnectionStringBuilder(connectionString);
var dbServer = builder.DataSource;
var dbName = builder.InitialCatalog;

SqlConnectionStringBuilder还可以用来创建连接字符串。 

var builder = new SqlConnectionStringBuilder();
builder["Data Source"] = "localhost";
builder.Add("Initial Catalog", "Demo");
builder.UserID = "sa";
builder.Password = "test";
builder.ApplicationName = "MyApp";
var connectionString = builder.ConnectionString;
