Try replicating my code in above image, or please attach your code.
Hi,
I just found the problem If we use Build Data table after creating the new instantiation
Dt=new DataTable(“Kitti”);
and then if we print
ds.tables(0).tablename.tostring()-- Output —> TableName
otherwise its printing properly. Why is this happening???
Please add a reproduction workflow - it will make it easier for all to debug and see if it’s something wrong with the way you used the code or is there an actual bug.
Preferably include there a sample that works and the one that doesn’t - usually you’ll see what’s going on when doing those anyway.
Regards.
brilliant explanation.

Hi Team,
Invoke method implementation is quite simple, this is used when we try to implement something beyond our builtin activities. You can use this activity to invoke a method of a Nonstatic or Static class.
Steps for invoke Method implementation:
Example using Static Class
1 Create a .net Class Library project.
2. Create a non_static class having a non static method on it.
(Make sure that you have added the required namespace: System.Activities.presentation.Metadata and System.ComponentModel)
3 Build the project in release mode.
4 Create a nuget package and save to the the activities location in your system"UiPath\app-17.1.6522".
5 install the nuget package to the UiPath Project.
Target Type: If the class is non ststic then keep the Target type as null.
Target Object: Create a instance of the class.ex new ClassLibrary1.Validate
Method Name: Provide the method name, ex ValidateString
Pass the result to a variable, ex result
Task is complete
With Static Method
TargetType Target Type must be the class instance.
Thanks,

Cool! That’s exactly what I want!
But I am confused with two points:
4 Create a nuget package and save to the the activities location in your system"UiPath\app-17.1.6522".
5 install the nuget package to the UiPath Project
How can I create a Nugget Package?
And more important, How can I Install a nugget Package in UIPath Project?
Please read this post to create a Nuget Package.
Hii
How i can move that folder which contains both json and image files from one directory to another directory? In Uipath
Please help me regarding this issues. Need workflow for this .
Get the files count from the directory (json and image ) and then use move file activity to move to another directory in a loop
or use .net method
Directory.Move(sourceDirectory, destinationDirectory);
Thank You
Can u please provide workflow.
Thank’s for this,
But it only copy all the folders to another folder. I want to copy the folder which contains json and image files.
I was struggling how to use InvokeMethod activity to invoke Array.Resize method.
It always failed with error:
‘Array’ does not have a public static method named ‘Resize’ matching the parameter types, generic type arguments, and generic type constraints supplied to InvokeMethod ‘Invoke Method - Array Resize’.
Finally I learned that Array.Resize is a generic static method which require besides Parameters also define GenericTypeArguments
Below picture illustrates the set-up of InvokeMethod for invoking generic static method.
Cheers
