| SqlPersistenceProviderFactory(String) |
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string. |
| SqlPersistenceProviderFactory(String, Boolean) |
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string and |
| SqlPersistenceProviderFactory(String, Boolean, TimeSpan) |
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string, |
Remarks
Overloads of the constructor for the SqlPersistenceProviderFactory class provide parameters for setting the following:
The connection string used for accessing the SQL database.
The lock time-out used for defining lock ownership duration.
Whether the persistence data is serialized as XML or binary data.
SqlPersistenceProviderFactory(NameValueCollection)
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified parameter collection.
public:
SqlPersistenceProviderFactory(System::Collections::Specialized::NameValueCollection ^ parameters);public SqlPersistenceProviderFactory (System.Collections.Specialized.NameValueCollection parameters);new System.ServiceModel.Persistence.SqlPersistenceProviderFactory : System.Collections.Specialized.NameValueCollection -> System.ServiceModel.Persistence.SqlPersistenceProviderFactoryPublic Sub New (parameters As NameValueCollection)Parameters
- parameters
- NameValueCollection
The collection of parameters used by the new persistence provider factory. Valid parameters include lockTimeout, connectionStringName, and serializeAsText.
Examples
The following code example shows how to create a new instance of the SqlPersistenceProviderFactory class using a parameters collection.
NameValueCollection parameters = new NameValueCollection();
parameters.Add("connectionStringName", DataBaseConstants.ConnectionString);
parameters.Add("lockTimeout", "00:01:00");
parameters.Add("serializeAsText", "false");
SqlPersistenceProviderFactory factory = new SqlPersistenceProviderFactory(
parameters);
Remarks
This constructor can be used to arbitrarily specify lockTimeout, connectionString, and serializeAsText without specifying the other parameters as required by the other constructors (for example, to specify the connectionString and lockTimeout parameters without specifying the serializeAsText parameter.)
Applies to
SqlPersistenceProviderFactory(String)
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string.
public:
SqlPersistenceProviderFactory(System::String ^ connectionString);public SqlPersistenceProviderFactory (string connectionString);new System.ServiceModel.Persistence.SqlPersistenceProviderFactory : string -> System.ServiceModel.Persistence.SqlPersistenceProviderFactoryPublic Sub New (connectionString As String)Parameters
- connectionString
- String
The connection parameters for the new persistence provider instance.
Examples
The following code example shows how to create a new instance of the SqlPersistenceProviderFactory class using a connection string.
SqlPersistenceProviderFactory factory = new SqlPersistenceProviderFactory(
DataBaseConstants.ConnectionString);
Applies to
SqlPersistenceProviderFactory(String, Boolean)
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string and serializeAsText parameters.
public:
SqlPersistenceProviderFactory(System::String ^ connectionString, bool serializeAsText);public SqlPersistenceProviderFactory (string connectionString, bool serializeAsText);new System.ServiceModel.Persistence.SqlPersistenceProviderFactory : string * bool -> System.ServiceModel.Persistence.SqlPersistenceProviderFactoryPublic Sub New (connectionString As String, serializeAsText As Boolean)Parameters
- connectionString
- String
The connection parameters for the new persistence provider instance.
- serializeAsText
- Boolean
Specifies whether data is serialized as text rather than binary.
Examples
The following code example shows how to create a new instance of the SqlPersistenceProviderFactory class.
SqlPersistenceProviderFactory factory = new SqlPersistenceProviderFactory(
DataBaseConstants.ConnectionString,
false);
Remarks
The default value for serializeAsText is false, which indicates that persistence information is serialized as binary data.
Applies to
SqlPersistenceProviderFactory(String, Boolean, TimeSpan)
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string, serializeAsText, and lockTimeout parameters.
public:
SqlPersistenceProviderFactory(System::String ^ connectionString, bool serializeAsText, TimeSpan lockTimeout);public SqlPersistenceProviderFactory (string connectionString, bool serializeAsText, TimeSpan lockTimeout);new System.ServiceModel.Persistence.SqlPersistenceProviderFactory : string * bool * TimeSpan -> System.ServiceModel.Persistence.SqlPersistenceProviderFactoryPublic Sub New (connectionString As String, serializeAsText As Boolean, lockTimeout As TimeSpan)Parameters
- connectionString
- String
The connection parameters for the new persistence provider factory instance.
- serializeAsText
- Boolean
Specifies whether data is serialized as text rather than binary.
- lockTimeout
- TimeSpan
The time-out for lock ownership. Locked instances are automatically unlocked after this time period. A time-out of TimeSpan.Zero specifies that no locking is used.
Examples
The following code example shows how to create a new instance of the SqlPersistenceProviderFactory class.
SqlPersistenceProviderFactory factory = new SqlPersistenceProviderFactory(
DataBaseConstants.ConnectionString,
false,
TimeSpan.FromSeconds(60));
Remarks
The default value for serializeAsText is false, which indicates that persistence information is serialized as binary data.
The default value for lockTimeout is TimeSpan.Zero, which indicates that locking is not used. If TimeSpan.MaxValue is used, then locks are maintained indefinitely.
