SqlConnectionStringBuilder::AttachDBFilename Property

.NET Framework (current version)
 

Gets or sets a string that contains the name of the primary data file. This includes the full path name of an attachable database.

Namespace:   System.Data.SqlClient
Assembly:  System.Data (in System.Data.dll)

C#
C++
F#
VB
Copy 
public:
property String^ AttachDBFilename {
	String^ get();
	void set(String^ value);
}

Property Value

Type: System::String^

The value of the AttachDBFilename property, or String.Empty if no value has been supplied.

Exception Condition
ArgumentNullException

To set the value to null, use Value.

This property corresponds to the "AttachDBFilename", "extended properties", and "initial file name" keys within the connection string.

AttachDBFilename is only supported for primary data files with an .mdf extension.

An error will be generated if a log file exists in the same directory as the data file and the 'database' keyword is used when attaching the primary data file. In this case, remove the log file. Once the database is attached, a new log file will be automatically generated based on the physical path.

The following example creates a new SqlConnectionStringBuilder instance, and sets the AttachDBFilename property in order to specify the name of an attached data file.
