CSharp C# Build XAML- Variables and Arguments - Read and Write quick examples

Introduction:

I found that the working with XAML variables and arguments between the XAML and C# CodeActivity was a bit of a pain so I put together the three most common situations to use as a cheat sheet.

Three examples follows:

CSharp C# Build XAML Variable as an Variable

CSharp  C# TFS Build  example of how to GET and SET an XAML variable

Read/Write XAML visual:

 

Code snippet:

string subDirectoryForTestRun = @"c:\MySubDirectory";                        context.DataContext.GetProperties()["TestSubdirectoryLocation"].SetValue(context.DataContext, subDirectoryForTestRun);                        var myVar = context.DataContext.GetProperties().Find("TestSubdirectoryLocation", true);             var myValue = myVar.GetValue(context.DataContext);             Console.WriteLine("myValue={0}", myValue);

CSharp C# Build XAML InArgument As InArgument Example

[Microsoft.TeamFoundation.Build.Client.BuildActivity(Microsoft.TeamFoundation.Build.Client.HostEnvironmentOption.All)]        public sealed class LaunchUnattendedTests : CodeActivity<bool>     {         public InArgument<IBuildDetail> BuildDetail { get; set; }         public InArgument<string> TestSeriesManagerLocation { get; set; }         public InArgument<UnattendedTestInfo> TestTargetInfoParameter { get; set; }         protected override bool Execute(CodeActivityContext context)         {             string TestSeriesManagerLocationNow = context.GetValue(this.TestSeriesManagerLocation);

CSharp C# Build XAML Variable as an InArgument

[Microsoft.TeamFoundation.Build.Client.BuildActivity(Microsoft.TeamFoundation.Build.Client.HostEnvironmentOption.All)]        public sealed class LaunchUnattendedTests : CodeActivity<bool>     {         public InArgument<IBuildDetail> BuildDetail { get; set; }         public InArgument<string> TestSeriesManagerLocation { get; set; }         public InArgument<UnattendedTestInfo> TestTargetInfoParameter { get; set; }         protected override bool Execute(CodeActivityContext context)         {             IBuildDetail ibd = context.GetValue(this.BuildDetail);             string BuildOutputPathFull = ibd.DropLocation;
