Quick Reference

.NET Wrapper Reference

This document covers the following topics:


Attributes

Attribute classes are defined and implemented in the .NET Wrapper runtime and used in the C# client interface object code to hold information extracted from the IDL file.

EntireXVersionAttribute

This attribute contains version information.

Example

[EntireXVersion("10.5.0.0")]
public class Example

LibraryAttribute

This attribute contains the library name.

Example

[Library("EXAMPLE")]
public class Example

BrokerAttribute

This attribute contains the Broker ID.

Example (without SSL)

[Broker("localhost:1971")]
public class Example

Example (with SSL)

[Broker("ssl://localhost:22101?trust_store=C:\SoftwareAG\EntireX/etc/ExxCACert.jks&key_store=C:\SoftwareAG\EntireX/etc/ExxJavaAppCert.jks&key_passwd=ExxJavaAppCert")]
public class Example

ServiceAttribute

This attribute contains the service name.

Example

[Service("RPC/SRV1/CALLNAT")]
public class Example

ProgramAttribute

This attribute contains the program name.

Example

[Program("CALC")]
public int Calculator(
  [SendAs(IdlType.A, Length=1f)][In] string operation,
  [SendAs(IdlType.I4)][In] int operand1,
  [SendAs(IdlType.I4)][In] int operand2
)

SendAsAttribute

This attribute contains type, length (fixed or dynamic) and dimension (fixed or dynamic) information.

Direction Attributes (In, Out)

These attributes contain direction information. They are supported natively by C#.

Example

[Program("HELLO")]
public void Hello(
  [SendAs(IdlType.A, Length=80f)][In] string client,
  [SendAs(IdlType.A, Length=80f)][In, Out] ref StringBuilder mail
)

Classes

The .NET Wrapper runtime defines and implements several generic service classes that are used in the generated C# client interface object and by .NET client applications.

BigNumeric

Implementation of decimal values without upper and lower limit and a default number of 99 digits after the decimal sign.

Constructors

public BigNumeric (  BigNumeric number )

Copy Constructor.

public BigNumeric (  decimal number )

Constructor translating a decimal number into a BigNumeric value.

public BigNumeric (  Int32 number )

Constructor translating an Int32 number into a BigNumeric value.

public BigNumeric (  Int64 number )

Constructor translating an Int64 number into a BigNumeric value.

public BigNumeric (  double number )

Constructor translating a double to its exact BigNumeric representation.

public BigNumeric (  string number )

Constructor converting the string representation of a number into a BigNumeric object. The string representation consists of an optional sign, '+' or '-', followed by a sequence of zero or more decimal digits, optionally followed by a fraction which consists of a decimal point followed by zero or more decimal digits and optionally followed by an exponent which consists of the character 'e' or 'E' followed by one or more decimal digits. The value must not exceed the size of the N(U)/P(U) data type.

public BigNumeric (  string number , CulturInfo info )

Constructor converting the string representation of a number into a BigNumeric object. The desired culture info is used to interpret the numeric string.

Methods

public int GetHashCode()

public BigNumeric Truncate (  int scale )

Returns a new BigNumeric with a maximum number of digits after the decimal sign. The number is truncated to the desired precision if necessary.

public BigNumeric Round (  int scale )

Returns a new BigNumeric with a maximum number of digits after the decimal sign. The number is rounded to the desired precision if necessary. Rounding is performed according to the rounding mode "HALF_UP" of Java class BigDecimal.

public unsafe object Invoke ( string library , string method , params object[] objArray )
where library is the name of the class in the generated client interface object
method the name of the method to be invoked
objArray the methods parameters as an array of objects - the array size must fit the parameter count of the method .

Invoke returns the result (if any) of the invoked method.

The initialisation of the parameter array follows the rules:

  1. Parameters of type groups, structs and arrays have to be assigned as follows

    int[] numbers = new int[10] ;
    ...
    objArray[i] = numbers ;
  2. [in,out] and [out] parameters of the simple data types bool, char, byte, sbyte, decimal, float, double, short, int and DateTime have to be assigned as follows:

    int number = 4711 ;
    ...
    objArray[i] = new Ref ( ref number )  ;

    where Ref is the class SoftwareAG.EntireX.NETWrapper.Runtime.Ref.

Note:
The name of the class and the assembly name (file name) have to be identical. For each class, a separate assembly is required. All these assemblies have to be placed in the folder of the client executable or have to be configured according to the rules described under .NET Framework Configuration in the RPC Server for .NET documentation.

Properties

public Encoding CharacterEncoding

Define an encoding for character translation. Default is System.Text.Encoding.GetEncoding(0) (current locale). See also the .NET Framework class library documentation for System.Text.Encoding.

public bool NaturalLogon

public Broker Broker

Sets or retrieves the Broker instance associated with the given Service instance.

public string RPCUserID

Sets or retrieves the RPC user ID of a given Service instance.

public string RPCPassword

public string ServerAddress

Retrieves the server address (class/server/service triplet) of a given Service instance.

public string Library

Sets or retrieves the library name of a given Service instance.

public Uint Timeout

Sets or retrieves the timeout value for a given Service instance. timeout = 0 is invalid. If 0 is set, a default of 50 seconds will be used.

public string CorrelationIDOfReply

Unique message (correlation) ID of reply part of the last RPC call. Available for EntireX Broker version 10.1 and higher. See Unique Message ID in the EntireX Broker ACI Programming documentation for detailed explanation of message IDs.

Example

Service service = new Service( broker, "RPC/SRV1/CALLNAT", "EXAMPLE");
service.UserIDAndPassword("RPC-USER", "RPC-Password");

XException

    };
    Output: "02150148: EntireX Broker not active.
