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:

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