ConnectionString Property (BigcommerceConnection)

Visual Basic
C#

'Declaration
 
Public Shadows Property ConnectionString As String

public new string ConnectionString {get; set;}

Property Value

The connection string that includes the parameters needed to establish the initial connection. The default value is an empty string ("").

When ConnectionString property is assigned a value, connection closes. Many of the connection string values have corresponding properties. When the connection string is set, all of these properties are updated, except when an error is detected. In this case, none of the properties are updated. BigcommerceConnection properties return only those settings contained in the ConnectionString.

Resetting the ConnectionString on a closed connection resets all connection string values (and related properties).

The connection string is parsed immediately after being set. If errors in syntax are found when parsing, a runtime exception, such as System.ArgumentException, is generated. Other errors can be found only when an attempt is made to Open the connection.

The ConnectionString is similar to an OLE DB connection string. Values may be delimited by single or double quotes, (for example, name='value' or name="value"). Either single or double quotes may be used within a connection string by using the other delimiter, for example, name="value's" or name= 'value"s', but not name= 'value's' or name= ""value"". All blank characters, except those placed within a value or within quotes, are ignored. Keyword value pairs must be separated by a semicolon (;). If a semicolon is part of a value, it also must be delimited by quotes. No escape sequences are supported. The value type is irrelevant. Names are not case sensitive. Arguments names may occur only once in the connection string.

The following table lists the valid names for values within the ConnectionString.

Name	Description
API Version	Determines the BigCommerce API version to use to interact with BigCommerce - v2 or v3. Note that BigCommerce API v3 does not support all the BigCommerce objects. Even if you use APIVersion.v3 in your connection, access to some objects is still performed via API v2. Besides the lists of objects and their structure is different for BigCommerce API v2 and API v3. See BigcommerceConnectionStringBuilder.APIVersion for more information.
API Version	Determines the BigCommerce API version to use: v2 or v3.
Access Token	The BigCommerce access token for OAuth authentication.
Authentication Token	The automatically generated key that is used for connecting to BigCommerce.
Authentication Type	Determines the authentication method to use: username/password or app center client. Supported values are Basic and OAuth. See AuthenticationType for more information.
Client ID	The BigCommerce client id for OAuth authentication.
Connection Lifetime	When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by Connection Lifetime. The default value is 0 (connection always returns to pool).
Connect Timeout -or- Connection Timeout	The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. The default value is 15.
Default Command Timeout	The time in seconds to wait while trying to execute a command before terminating the attempt and generating an error. A value of 0 indicates no limit.
Initialization Command	Specifies a data source-specific command that should be executed immediately after establishing the connection.
Max Pool Size	The maximum number of connections allowed in the pool. Setting the Max Pool Size value of the ConnectionString can affect performance. The default value is 100.
Min Pool Size	The minimum number of connections allowed in the pool. The default value is 0.
Persist Security Info	Indicates if security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state.
Pooling	If true, by default, the BigcommerceConnection object is drawn from the appropriate pool or is created and added to the appropriate pool.
Proxy Host	The host name or IP address of proxy server.
Proxy Password	The password for the proxy server account.
Proxy Port	The port number of the proxy server. The default value is 3128.
Proxy User	The proxy server account name.
Run Once Command	A command to execute when the connection is opened the first time and not executed when the connection is taken from the pool.
Readonly	Determines whether the connection is read-only (allows only SELECT statements).
Store Id	The id of your BigCommerce store. For OAuth authentication.
Server	The path where all XML requests to Bigcommerce should be sent.
Use Custom Fields	Determines whether you will be able to get product custom fields via the CustomFields field of the Products object through this connection. Applicable only for BigCommerce API v3 connections. Does not affect working with custom fields for customers and customer addresses, and it also does not affect access to product custom fields via the ProductCustomFields object.
User Id	The user name to login with.
UTC Dates	Indicates whether all the datetime values retrieved from the data source are returned as UTC values or converted to local time, and whether date values, specified on the application side (for example, in SQL statements) are considered UTC or local. Default value is false.

The following example creates a BigcommerceConnection and sets some of its properties in the connection string.

csharp

public void CreateBigcommerceConnection()
{
  string myConnString1 = 
     "Server=https://bigcommerce-store.mybigcommerce.com/api/v2/;User Id=User;Authentication Token=qweASDzcx1234567890rtyuiqweASDzcx1234567;";
  BigcommerceConnection bigcommerceConnection1 = new BigcommerceConnection(myConnString1);
  bigcommerceConnection1.Open();
}

Visual Basic

Public Sub CreateBigcommerceConnection()
  Dim myConnString1 As String = _
      "Server=https://bigcommerce-store.mybigcommerce.com/api/v2/;User Id=User;Authentication Token=qweASDzcx1234567890rtyuiqweASDzcx1234567;"
  Dim bigcommerceConnection1 As New BigcommerceConnection(myConnString1)
  bigcommerceConnection1.Open()
End Sub

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
