I'm using the Python .Net library so I don't have access to List<T>. Currently when I try to initialize an Array an error is thrown.

The documentation has an example that is throwing an error from the latest code base.

Ex:

from System import Array
myarray = Array[int](10) #TypeError: Cannot convert 10 to System.Int32[]

The following works on 64bit but not on 32bit! 

myarray = Array[int]([10]) #OverflowError: value too large to convert

    how about myarray = Array[int]([10])? Commented Jan 7, 2015 at 14:29
  • @njzk2 fairly certain this is a bug I should bring up to the maintainers Commented Jan 7, 2015 at 15:16

Reset to default
10

I also get an error when I execute Array[int](10). It looks like the expected argument isn't the size, but a Python list. The following works for me:

py_array = [1, 2, 3]
net_array = Array[int](py_array)

Now, net_array.Length should return 3.

This is the same example I have above, it works on 64-bit but not on 32-bit, this is most likely a bug in the package
I'm running PythonNet in 32-bit mode, and the example I gave above works fine.
How did you install Python .Net? The package maintainers were able to reproduce it here, github.com/pythonnet/pythonnet/issues/58
I got the source code from sourceforge.net/p/pythonnet/code/147/tree/trunk and compiled it for x86.

Use System.Array.CreateInstance(<type>, <length>)
