employee(C# 中Employee對象的作用是什么)

C# Employee對象

命令的名字是PRINTOUTEMPLOYEE。ListEmployee()函數接收一個ObjectId參數,它通過一個ref類型的字符串數組返回值(包含相應的雇員數據)。調用它的PrintoutEmployee()函數只是用來在命令行中輸出這些數據。

我們需要一個遍歷并顯示所有雇員數據的命令。

publicstaticvoidListEmployee(ObjectIdemployeeId,refstring[]saEmployeeList) 
{ 
intnEmployeeDataCount=0; 
Databasedb=HostApplicationServices.WorkingDatabase; 
Transactiontrans=db.TransactionManager.StartTransaction();//開始事務處理。 
try 
{ 
Entityent=(Entity)trans.GetObject(employeeId,OpenMode.ForRead,false);
//打開當前對象! 
if(ent.GetType()==typeof(BlockReference)) 
{ 
//不是所有的塊索引都有雇員數據,所以我們要處理錯誤 
boolbHasOurDict=true; 
XrecordEmployeeXRec=null; 
try{ 
BlockReferencebr=(BlockReference)ent; 
DBDictionaryextDict=(DBDictionary)trans.GetObject
(br.ExtensionDictionary,OpenMode.ForRead,false); 
EmployeeXRec=(Xrecord)trans.GetObject(extDict.GetAt("EmployeeData"),
OpenMode.ForRead,false); 
} 
catch 
{ 
bHasOurDict=false;//出現了錯誤……字典或擴展記錄不能訪問 
} 
if(bHasOurDict)//如果獲得擴展字典,而又有擴展記錄…… 
{ 
//為雇員列表分配內存 
saEmployeeList=newString[4]; 
//加入雇員的名字 
TypedValueresBuf=EmployeeXRec.Data.AsArray()[0]; 
saEmployeeList.SetValue(string.Format("{0}\n",resBuf.Value),
nEmployeeDataCount); 
nEmployeeDataCount+=1; 
//加入雇員的薪水 
resBuf=EmployeeXRec.Data.AsArray()[1]; 
saEmployeeList.SetValue(string.Format("{0}\n",resBuf.Value),
nEmployeeDataCount); 
nEmployeeDataCount+=1; 
//加入雇員所在的部門 
resBuf=EmployeeXRec.Data.AsArray()[2]; 
stringstr=(string)resBuf.Value; 
saEmployeeList.SetValue(string.Format("{0}\n",resBuf.Value),
nEmployeeDataCount); 
nEmployeeDataCount+=1; 
//現在,讓我們從公司字典中獲取老板的名字 
//在NOD中找到. 
DBDictionaryNOD=(DBDictionary)trans.GetObject(db.NamedObjectsDictionaryId,
OpenMode.ForRead,false); 
DBDictionaryacmeDict=(DBDictionary)trans.GetObject(NOD.GetAt("ACME_DIVISION"),
OpenMode.ForRead); 
//注意我們直接使用擴展數據... 
DBDictionarysalesDict=(DBDictionary)trans.GetObject(acmeDict.GetAt
((string)EmployeeXRec.Data.AsArray()[2].Value),OpenMode.ForRead); 
XrecordsalesXRec=(Xrecord)trans.GetObject(salesDict.GetAt("DepartmentManager"),
OpenMode.ForRead); 
//***,把雇員的數據輸出到命令行 
resBuf=salesXRec.Data.AsArray()[0]; 
saEmployeeList.SetValue(string.Format("{0}\n",resBuf.Value),nEmployeeDataCount); 
nEmployeeDataCount+=1; 
} 
} 
trans.Commit(); 
} 
finally 
{ 
trans.Dispose(); 
} 
} 
[CommandMethod("PRINTOUTEMPLOYEE")] 
publicstaticvoidPrintoutEmployee() 
{ 
Editored=Application.DocumentManager.MdiActiveDocument.Editor; 
//聲明我們將在下面使用的工具... 
Databasedb=HostApplicationServices.WorkingDatabase; 
Transactiontrans=db.TransactionManager.StartTransaction(); 
try 
{ 
//首先,獲取塊表和模型空間塊表記錄 
BlockTablebt=(BlockTable)trans.GetObject(HostApplicationServices.
WorkingDatabase.BlockTableId,OpenMode.ForRead); 
BlockTableRecordbtr=(BlockTableRecord)trans.GetObject(bt[BlockTableRecord.ModelSpace],
OpenMode.ForRead); 
//現在,我們需要把內容輸出到命令行。這里可以有一個對象幫助我們: 
//下面的部分,我們將遍歷模型空間: 
foreach(ObjectIdidinbtr) 
{ 
Entityent=(Entity)trans.GetObject(id,OpenMode.ForRead,false);//打開當前對象! 
if(entisBlockReference) 
{ 
string[]saEmployeeList=null;//這是正確的...定義新的列表。 
ListEmployee(id,refsaEmployeeList); 
if((saEmployeeList.Length==4)) 
{ 
ed.WriteMessage("EmployeeName:{0}",saEmployeeList[0]); 
ed.WriteMessage("EmployeeSalary:{0}",saEmployeeList[1]); 
ed.WriteMessage("EmployeeDivision:{0}",saEmployeeList[2]); 
ed.WriteMessage("DivisionManager:{0}",saEmployeeList[3]); 
} 
} 
} 
} 
finally

}
