msbuild - How edit or add properties in inline task -

i need invoke msbuild task properties, whats name can calculated in runtime. try scripts

main.xml

<?xml version="1.0" encoding="utf-8"?> <project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" toolsversion="14.0" defaulttargets="build">    <usingtask taskname="getvars" taskfactory="codetaskfactory" assemblyfile="$(msbuildtoolspath)\microsoft.build.tasks.v4.0.dll">             <parametergroup>       <result parametertype="system.string" output="true"/>     </parametergroup>     <task>       <code type="fragment" language="cs">         <![cdata[           this.result = "aaa=123;bbb=456;";         ]]>       </code>     </task>   </usingtask>    <propertygroup>     <vars></vars>   </propertygroup>    <target name="make">     <getvars>       <output taskparameter="result" propertyname="vars"/>     </getvars>      <msbuild projects="proj.xml" targets="make" properties="$(vars)"/>   </target> </project> 

proj.xml

<?xml version="1.0" encoding="utf-8"?> <project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" defaulttargets="build">     <target name="make">         <message text="aaa = $(aaa)"/>         <message text="bbb = $(bbb)"/>     </target> </project> 

this script give output:

aaa = 123;bbb=456; bbb = 

i expected output:

aaa = 123; bbb = 456;  

if want inline task produce several items (the msbuild equivalent of array or list in other languages), should state instead of using property (which single key/value pair). covered in of inline task documentation - uses full-blown itaskitems whereas using string array do. so:

• output system.string[] inline task
• assign item instead of property using itemname =
• pass item msbuild task (which expects anyway), using @() notation

in code:

<?xml version="1.0" encoding="utf-8"?> <project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" toolsversion="14.0" defaulttargets="make">    <usingtask taskname="getvars" taskfactory="codetaskfactory" assemblyfile="$(msbuildtoolspath)\microsoft.build.tasks.v4.0.dll">             <parametergroup>       <result parametertype="system.string[]" output="true"/>     </parametergroup>     <task>       <code type="fragment" language="cs">         <![cdata[           this.result = new system.string[]{"aaa=123", "bbb=456"};         ]]>       </code>     </task>   </usingtask>    <target name="make">     <getvars>       <output taskparameter="result" itemname="vars"/>     </getvars>     <msbuild projects="$(msbuildthisfile)" targets="show" properties="@(vars)"/>   </target>    <target name="show">     <message text="aaa = $(aaa)"/>     <message text="bbb = $(bbb)"/>   </target> </project> 

output:

show:   aaa = 123   bbb = 456
