C

channel

A defined mechanism for remote components to communicate with one another. The channel definition includes protocol (such as HTTP or TCP), port numbers, and (optionally) security features.

class

The source code that defines an object.

ClassInterfaceAttribute

An attribute that can be applied to an assembly or class and that causes a COM interface to be generated automatically for your .NET component.

client-activated

A .NET Remoting object can be configured as either client-activated or server-ativated. The lifetime of a client-activated remote object is controlled by the client; the object will remain activated on the server for multiple calls from the same caller.

Close method

This method of the Debug and Trace classes flushes the output buffers and closes the TraceListeners.

CLR Debugger (DbgCLR.exe)

A command-line utility that is provided with Visual Studio .NET. It provides debugging services with a graphical interface when the .NET Framework is installed but Visual Studio .NET is not present.

CLR role-based security

Grants permissions based on the identity of the user running the code and the roles to which they are assigned. It is often used to check whether a specific Windows user is authorized to access a particular system or network resource.

code access permissions

The capabilities that can be granted to applications, such as file and disk access, and access to other system resources.

code access security

Facilitates restricting the operation of code based on what the Common Language Runtime knows about the calling code. Code access security is implemented by combining .NET permissions with the concepts of evidence, security policies, and code groups.

code groups

Assemblies that are allowed similar permissions and are grouped together when defining security policy to simplify administration.

ColumnMapping property

Thisproperty of the DataColumn object controls whether a column is output as an XML element or as an attribute. The ColumnMapping property can be specified as either Element, Attribute, Hidden (that column will not be included in the XML output), or SimpleContent (the column data will be output as the text content of the row element).

COM+

A name that describes the Component Object Model (COM) and Windows Component Services as implemented on the Windows 2000 platform.

COM+ proxies

Wrappers that mimic the interface of the COM+ component locally, but contain only the code necessary to make a call to the COM+ application in another process or on another computer.

CommandBehavior

An optional parameter of the Command.ExecuteReader method. The most common use for this parameter is to take advantage of the CloseConnection option, but it can also be used for other optimizations, such as processing single row resultsets.

CommandText property

A property of the ADO.NET Command class. Use it to specify either a SQL statement, stored procedure name, or the name of a database table.

CommandType property

A property of the ADO.NET Command class. Use it to specify the type of query that will be run: an ad hoc SQL query (text), a stored procedure, or direct table access.

component

A compiled unit of executable code.

component interoperability

A set of standard interfaces that enable components to discover the capabilities of other components and call their methods.

Component Services tool

A Windows operating system utility enabling s you to manage components that are hosted by COM+ Component services and .NET Enterprise Services.

ComVisibleAttribute

An attribute that can be applied to a class or member of a .NET assembly to determine whether the class or member is available to COM components that are interoperating with the assembly.

connection pooling

A mechanism that maintains a group of already initialized connections to the database. When a user requests a connection, an existing one in the pool can be made available quickly. When the user releases the connection, it can be returned to the pool and recycled for the next user.

Connection.BeginTransaction method

Use the BeginTransaction method of the ADO.NET Connection class to create an ADO.NET Transaction object.

ConnectionString property

A property of the ADO.NET Connection class. It specifies the type of database server, location of the server, database name, user credentials, and other settings.

ContextUtil class

The System.EnterpriseServices.ContextUtil class has properties that give you information about the status of the current transaction and has methods that you can use to affect transaction outcome.

ContinueUpdateOnError property

This property of the ADO.NET DataAdapter determines whether the DataAdapter.Update method will stop processing when an error is encountered, or continue processing any remaining records and mark those rows in the DataSet where the update operation failed.

CreateAttribute method

This method of the XmlDocument class enables you to create new XML attributes programmatically.

CreateElement method

This method of the XmlDocument class enables you to create new XML elements programmatically.

cryptography

The process of encoding data to an unrecognizable form (known as ciphertext) for the sake of secrecy, and decoding it to obtain the original data (known as plaintext).

CryptoStream class

A member of the System.Security.Cryptography namespace, this class can read input data and write it as encrypted output to a stream object.
