Python for. Net scripts call the DOTNET framework (ref and out parameter problems)

Pythonnet is similar to ironpython but is definitely different. Pythonnet allows you to write scripts to call. NET Framework or your own DLL. Is an open source project on SourceForge. The usage is to download a python interpreter. After installation, replace the original version with the corresponding version of the downloaded python. Net file. Http://pythonnet.sourceforge.net/, supporting to DOTNET 2.0.

For example, download Python 2.5 to C disk, path is c: \ python25, copy all the files in D: \ pythonnet-2.0-alpha2 \ python2.5-ucs2 directory to c: \ python25, now you can use it.

TryCode

  Import  System

  Class  Test ():
_ Id  =  0
_ Name =     "  123  "  
  Def     _ Init __  (Self, ID, name ):
Self. _ id  =  ID
Self. _ name  =  Name

  Def  Main ():
App  = Test (  123  ,  "  ASD  "  )
System. Console. writeline (App. _ id)
System. Console. writeline (App. _ name)
System. Console. readkey ()

  If     _ Name __     =     '  _ Main __  ' :
Main ()
 

 

This is a consoleProgramOf course, you can also do winform. However, I think using Python directly does not seem to be of any benefit, but it is still very good to use it for calling.

But C # contains ref and out values. What should I do? All references are passed in Python, but it does not seem to work here.

 

  Import  System as s
  Def  Main ():
M  =     "  123  " 
R  =  0
X  =  S. int32.tryparse (M, R)
S. Console. writeline (r)
S. Console. readkey ()
  If     _ Name __     =     '  _ Main __  '  :
Main () 

The output value of the above Code is 0, which is obviously incorrect. However, output X is garbled and its type is an array.

  Import  System as s
  Def  Main ():
M  =     "  123  "  
R  =  0
X  = S. int32.tryparse (M, R)
S. Console. writeline (X [0])
S. Console. writeline (X [  1  ])
S. Console. readkey ()
  If     _ Name __     =     '  _ Main __  '  :
Main ()
 

The code can be modified. Output the first 1 of 1123, which should be a true value, and 123 is the converted value. The same applies to ref values.

  Import  Sharpbot. engin as engin
  Import  Hopeutil. html as HTML
  Import  System as s
  Def  Main ():
App  =  Engin. defaultcrawler (  "  Http://www.163.com  " );
Result  =  Html. htmlsimpledom. htmlsimplemodel ()
Suc  =  App. responsestring (result)
  If  Suc [0]:
S. Console. writeline (Suc [  1  ]. Title)
S. Console. writeline (Suc [  1  ]. Metacharset)
S. Console. writeline (Suc [  1  ]. Body)
  Else :
S. Console. writeline (  123  )

  If     _ Name __     =     '  _ Main __  '  :
Main ()
 

The above responsestring parameter in C # Is (ref htmlsimpledom. htmlsimplemodel result ). It is also returned to the array. It feels good to use the script to test the crawler engine. Using a script to operate DOTNET is different.
