Python的说明

在Python中可以调用C#宿主中的功能（clr.AddReference('Business')）。 

import clr
import io
import os
import stringclr.AddReference('System')
clr.AddReference('System.Data')
clr.AddReference('Business')from System import *
from System.Data import *
from Business import *def get_account_money_by_dt(account_id,date):db=Pub.db_name_mgrInitMoney=Pub.select_str(db,"select InitMoney from account where account_id="+account_id)cash=Pub.select_str(db,"select sum(amount_real) from tran where account_id="+account_id+" and tran_date<="+date)stock_amount=float.Parse("0")table_stock=Pub.select(db,"select code_type,code,sum(tran_count_real) as c from tran where account_id="+account_id+" and code<>'' and tran_date<="+date +" group by code_type,code")for dr in table_stock.Rows:code_type=DBUtils.get_str(dr, "code_type");code=DBUtils.get_str(dr, "code");count=DBUtils.get_str(dr, "c");price=Pub.select_str(code_type+"\\"+code,"select close from data_day where dt<="+date+" order by dt desc limit 1")if price<>'':stock_amount=stock_amount+float.Parse(price)*float.Parse(count)if cash=="":cash="0"if InitMoney=="":InitMoney="0"return (float.Parse(InitMoney)+float.Parse(cash)+stock_amount).ToString("0.00")

C#的说明

加载Python环境

            instance = new Py();
            instance.init_py_lib();

        public void init_py_lib(){engine = IronPython.Hosting.Python.CreateEngine();scope = engine.CreateScope();engine.Runtime.IO.SetOutput(Output,Encoding.Unicode);engine.SetTrace(on_trace);StringBuilder sb = new StringBuilder();sb.AppendLine(@"import sys ");sb.AppendLine(@"sys.path.append("".\py\Lib.zip"") ");sb.AppendLine(@"sys.path.append("".\scripts"") ");ScriptSource source = engine.CreateScriptSourceFromString(sb.ToString());source.Execute(scope);string init_py = Pub.exe_dir + @"\py\init.py";if (System.IO.File.Exists(init_py)){ScriptSource source_init = engine.CreateScriptSourceFromFile(init_py);source_init.Execute(scope);}}

执行脚本

 

       public Boolean Execute(string script, out string msg, out IronPyErrors err, ExecRequest request){msg = "";err = new IronPyErrors();StringBuilder sb = request.log;sb.AppendLine("开始 "+DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") );sb.AppendLine("------");try{last_trace_lineno = "";last_trace_result = "";ScriptSource source = engine.CreateScriptSourceFromString(script);                CompiledCode cc = source.Compile(err);  if (err.Items.Count > 0){err.ToStringBuilder(sb);msg = "编译错误";sb.Append(msg);return false;}scope.SetVariable("request", request);Py.instance.Output.SetLength(0);string sql_err = DataAccess.DataConn.clear_err();cc.Execute(scope);               Py.instance.Output.Flush();string print_s = Encoding.Unicode.GetString(Py.instance.Output.ToArray());sql_err = DataAccess.DataConn.clear_err();if (sql_err != "")sb.AppendLine(sql_err);sb.AppendLine(print_s);sb.AppendLine("------");msg = "运行完成 "+ DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") ;sb.Append(msg);return true;}catch (Exception e){if (last_trace_lineno != "")msg = "trace line:" + last_trace_lineno;if (last_trace_result != "")msg = msg + " " + "trace:" + last_trace_result;msg = msg + " " + e.Message;sb.Append(msg);}return false;}
