Compiles C# source into executables or modules. csc.exe on Windows or mcs on any other platform must be on the execute path, unless another executable or the full path to that executable is specified in the executable parameter

All parameters are optional: <csc/> should suffice to produce a debug build of all *.cs files. However, naming an destFilestops the csc compiler from choosing an output name from random, and allows the dependency checker to determine if the file is out of date.

The task is a directory based task, so attributes like includes="*.cs" and excludes="broken.cs" can be used to control the files pulled in. By default, all *.cs files from the project folder down are included in the command. When this happens the output file -if not specified- is taken as the first file in the list, which may be somewhat hard to control. Specifying the output file with destFile seems prudent.

For more complex source trees, nested src elemements can be supplied. When such an element is present, the implicit fileset is ignored. This makes sense, when you think about it :)

References to external files can be made through the references attribute, or (since Ant1.6), via nested <reference> filesets. With the latter, the timestamps of the references are also used in the dependency checking algorithm.

Example

<csc optimize="true" debug="false" docFile="documentation.xml" warnLevel="4" unsafe="false" targetType="exe" incremental="false" mainClass = "MainApp" destFile="NetApp.exe" > <src dir="src" includes="*.cs" /> <reference file="${testCSC.dll}" /> <define name="RELEASE" /> <define name="DEBUG" if="debug.property"/> <define name="def3" unless="def3.property"/> </csc> 

Attribute	Description	Type	Requirement
additionalmodules	Semicolon separated list of modules to refer to.	String	Optional
debug	set the debug flag on or off.	boolean
definitions	Semicolon separated list of defined constants.	String
destdir	Set the destination directory of files to be compiled.	File
destfile	Set the name of exe/library to create.	File
docfile	file for generated XML documentation	File
executable	set the name of the program, overriding the defaults. Can be used to set the full path to a program, or to switch to an alternate implementation of the command, such as the Mono or Rotor versions -provided they use the same command line arguments as the .NET framework edition	String
extraoptions	Any extra options which are not explicitly supported by this task.	String
failonerror	If true, fail on compilation errors.	boolean
filealign	Set the file alignment. Valid values are 0,512, 1024, 2048, 4096, 8192, and 16384, 0 means 'leave to the compiler'	int
fullpaths	If true, print the full path of files on errors.	boolean
includedefaultreferences	If true, automatically includes the common assemblies in dotnet, and tells the compiler to link in mscore.dll. set the automatic reference inclusion flag on or off this flag controls the /nostdlib option in CSC	boolean
incremental	set the incremental compilation flag on or off.	boolean
mainclass	Sets the name of main class for executables.	String
noconfig	A flag that tells the compiler not to read in the compiler settings files 'csc.rsp' in its bin directory and then the local directory	boolean
optimize	If true, enables optimization flag.	boolean
outputfile	The output file. This is identical to the destFile attribute.	File
referencefiles	Path of references to include. Wildcards should work.	Path
references	Semicolon separated list of DLLs to refer to.	String
srcdir	Set the source directory of the files to be compiled.	File
targettype	set the target type to one of exe|library|module|winexe	"exe", "library", "module", "winexe"
unsafe	If true, enables the unsafe keyword.	boolean
utf8output	If true, require all compiler output to be in UTF8 format.	boolean
warnlevel	Level of warning currently between 1 and 4 with 4 being the strictest.	int
win32icon	Set the filename of icon to include.	File
win32res	Sets the filename of a win32 resource (.RES) file to include. This is not a .NET resource, but what Windows is used to.	File
