Ikvm:java Code C # calls

Encountered in the work of the docking Java interface, involving Java encryption or signature problems,. NET cannot be real. Edit the Java code as a DLL to a. NET call

Note: This is only done with simple Java code processing and does not involve complex Java packages

Java File Processing:

The first step: simple Java code

Package com.zht; // C # namespaces  Public class TESTAAA {    public  String returnstring () {        return"Hello, zht! " ;    }}

Step Two: Java code is compiled into a class file

1: In the Start menu, enter "cmd" in the search box and enter ease;
2: Switch to the Java file storage path;
3: Enter "Javac file name. Java" To compile the Java file into a class file.
Note: The prerequisite is to download the JDK and configure the environment variables.

Step Three: Package the class file

1: In the Start menu, enter "cmd" in the search box and enter ease;
2: Switch to the Java file storage path;
3: Enter "jar CVF file name. jar Directory Name" to convert the directory to a. jar file.

IKVM processing

The first step: Download IKVM Required components to the IKVM official website http://www.ikvm.net/

Ikvmbin-7.2.4630.5.zip (i download the latest version)

Step two: Set the IKVM environment variable

Unzip the Ikvm-0.42.0.3.zip and add the%ikvm_home%/bin to the path. The%ikvm_home% here refers to the IKVM home directory after decompression.

Step three: convert the Java jar package to a. dll control

Command used: Ikvmc-out:ikvm.dll Test.jar

Where IKVM.dll is the file name of the. dll control that will be generated; Test.jar is the jar package file that was previously packaged.

Fourth Step: Add the required controls to your C # project

1. Create a new C #. NET project, first add the necessary DLLs

%IKVM_HOME%/BIN/IKVM. OpenJDK.Core.dll

%IKVM_HOME%/BIN/IKVM. Runtime.dll

%IKVM_HOME%/BIN/IKVM. Runtime.JNI.dll

2. Add the generated. dll file

To load a previously generated. dll file into a C # project

Fifth Step: Test

Java classes are used in C # projects in the same way as Java. But the reference to the package uses the syntax using C #
