ADO.NET数据库连接池

we specify the pooling characteristics in the connection string when the SqlConnection is constructed, as shown in the following code sample. Please note: Pooling is implicit, you automatically get it unless you disable it. Therefore, "true" is the default for the pooling keyword (pooling=true).

String connString;

//  Specification in the connection string:
//  Please note: Pooling is implicit, you automatically get it unless you disable it. 
//  Therefore, "true" is the default for the pooling keyword (pooling=true).   
//  Connection Reset:    False
//  Connection Lifetime: 5

//  Min Pool Size:       1
//  Max Pool Size:       50

connString  =   " server=(local)\NetSDK;Integrated Security=SSPI;database=northwind; "   +
