获得当前数据库的名字或在连接打开后使用的数据库名字。

 语法

[Visual Basic]

Public Overrides ReadOnly Property Database As String

Get

[C#]

public override string Database { get; }

 实现

IDbConnection.Database

 注释

Database 属性不能动态更新，如果用户想改变数据库可以使用ChangeDatabase 方法改变当前数据库，此时这个属性会变为新的数据库值。

 示例

下面的例子创建了一个 GBaseConnection 并且显示了它的一些只读属性。

[Visual Basic]

Public Sub CreateGBaseConnection()

Dim gsConnString As String = _

"Persist SecurityInfo=False;

database=test;server=localhost;"_

&"user id=joeuser;pwd=pass;pooling=false"

Dim gsConnection As New GBaseConnection( gsConnString )

gsConnection.Open()

MessageBox.Show( "Server Version: " +

gsConnection.ServerVersion _

+ ControlChars.NewLine + "Database: " +_

gsConnection.Database )

gsConnection.ChangeDatabase( "test2" )

MessageBox.Show( "ServerVersion: " +

gsConnection.ServerVersion _

+ ControlChars.NewLine + "Database: " +_

gsConnection.Database )

gsConnection.Close()

End Sub

[C#]

public void CreateGBaseConnection()

{

string gsConnString = "Persist Security

Info=False;database=test;server=localhost;user

id=joeuser;pwd=pass;pooling=false";

GBaseConnection gsConnection = new

GBaseConnection( gsConnString );

gsConnection.Open();

MessageBox.Show( "Server Version: " +

gsConnection.ServerVersion + "\nDatabase: " + gsConnection.Database );

gsConnection.ChangeDatabase( "test2" );

MessageBox.Show( "ServerVersion: " +

gsConnection.ServerVersion + "\nDatabase: " + gsConnection.Database );

gsConnection.Close();

}
