Connecting from Code
The CData ADO.NET Provider for Neo4j implements a standard DbConnection object in Neo4jConnection. You can also use the Neo4jConnectionStringBuilder to programmatically build, parse, and rebuild connection strings.
Creating Connection Objects
See Establishing a Connection for guides to defining the connection string and authenticating. Below is a typical invocation to create Neo4jConnection objects.
C#
using (Neo4jConnection connection =
new Neo4jConnection("server=localhost;port=7474;user=neo4j;password=password;"))
{
connection.Open();
}
VB.NET
Using connection As New Neo4jConnection("server=localhost;port=7474;user=neo4j;password=password;")
connection.Open
End Using
Using Neo4jConnectionStringBuilder
The following code example shows how to use an ADO.NET connection string builder to parse a connection string.
C#
Neo4jConnectionStringBuilder builder =
new Neo4jConnectionStringBuilder("server=localhost;port=7474;user=neo4j;password=password;");
//Pass the connection string builder an existing connection string, and you can get and set any of the elements as strongly typed properties.
builder.ConnectionString = "server=localhost;port=7474;user=neo4j;password=password;";
//Now that the connection string has been parsed,
// you can work with individual items:
builder.MyString = "new property";
builder.MyBoolean = true;
// You can refer to connection keys using strings,
// as well.
builder["Logfile"] = "test.log";
builder["Verbosity"] = 5;
VB.NET
Dim builder As Neo4jConnectionStringBuilder = New Neo4jConnectionStringBuilder("server=localhost;port=7474;user=neo4j;password=password;")
'Pass the connection string builder an existing connection string, and you can get and set any of the elements using strongly typed properties.
builder.ConnectionString = server=localhost;port=7474;user=neo4j;password=password;"
'Now that the connection string has been parsed,
' you can work with individual items:
builder.MyString = "new property"
builder.MyBoolean = True
' You can refer to connection keys using strings,
' as well.
builder("Logfile") = "test.log"
builder("Verbosity") = 5
