ASP. NET two languages: J # And C ++

Source: Internet

In the DataTable and DataReader operations, we can see that J # And C ++ use the get_Item () function in a large number. I estimate that both J # And C ++ undergo Object transformation, it may have a slight impact on performance.

Using these two languages to create ASP. NET may be useful to friends who are used to C ++ and JAVA.

I believe that each language has its own strengths. Everyone learns from each other and constructs a good overall structure. I have seen many C # beginners who seem to be interested in VB. NET is biased, and "never use VB" is the glory. Some friends, J # And C ++. net has little knowledge about it, so I misunderstand that these two languages are useless. In fact, these understandings are one-sided.

For example:

  1. /* Jscript | Jscript.Net */  
  2. var conn = Server.CreateObject("ADODB.Connection");  
  3. conn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data 
  4. var rs = conn.Execute("SELECT * FROM image_data");  
  5. while(!rs.EOF)  
  6. {  
  7. Response.Write(rs("title").value);  
  8. rs.MoveNext();  
  9. }  
  10. rs.Close();  
  11. conn.Close(); 

You don't need to think that this is only ASP, which is also the ASP. NET of the geographic path. Although in our. in the eyes of NET developers, the reputation of RecordSet may not be as good as that of DataReader, but this is not covered in this article. Here we only say: if C # is used to implement the same functions above, the result can only be slow execution, long code, and complex structure.

In ASP. NET, no language is the best or the worst language. Each of the five languages has its own strengths and weaknesses. All of them generate the IL intermediate code. That is to say, J # And C ++ are inherently compatible with each other, which is ASP.. NET.
