asp.net中獲取新增加記錄的ID Access版

更新時間：2012年03月01日 20:44:03 作者：

在實際開發(fā)中有時需要獲取新增加的記錄的ID。如以新增加ID為文件名生成靜態(tài)頁等

這里參考了Erist.Protal里的代碼

 
/// <summary> 
/// 增加新的文章 
/// </summary> 
/// <param name="ArticleTitle"></param> 
/// <param name="Author"></param> 
/// <param name="ArticleFrom"></param> 
/// <param name="Creator"></param> 
/// <param name="ModifyBy"></param> 
/// <param name="Content"></param> 
/// <param name="ChannelID"></param> 
/// <param name="IsOnTop"></param> 
/// <param name="IsCommend"></param> 
/// <param name="IsCheck"></param> 
/// <param name="Keyword"></param> 
/// <param name="ArticleIntroduction"></param> 
/// <returns>新增加文章的ID</returns> 
public int AddArticle(string ArticleTitle, 
string Author, 
string ArticleFrom, 
int Creator, 
int ModifyBy, 
string Content, 
int ChannelID, 
bool IsOnTop, 
bool IsCommend, 
bool IsCheck, 
string Keyword, 
string ArticleIntroduction) 
{ 
int ArticleID =-1; 
//格式化HTML標記 
ArticleTitle=System.Web.HttpUtility.HtmlEncode(ArticleTitle); 
Author=System.Web.HttpUtility.HtmlEncode(Author); 
Keyword=System.Web.HttpUtility.HtmlEncode(Keyword); 

OleDbConnection OleCon=new OleDbConnection(Globals.ConnectString); 
OleDbCommand OleCmd=new OleDbCommand(); 
OleCmd.CommandType=System.Data.CommandType.StoredProcedure; 
OleCmd.Connection=OleCon; 
OleCmd.CommandText="AddArticle"; 
//取得下一個ID號 
ArticleID= Erist.Common.Data.DataProvider.GetAutoID("ArticleID","Article",Globals.ConnectString); 
OleCmd.Parameters.Add("ArticleID",ArticleID); 
OleCmd.Parameters.Add("ArticleTitle",ArticleTitle); 
OleCmd.Parameters.Add("Author",Author); 
OleCmd.Parameters.Add("ArticleFrom",ArticleFrom); 
OleCmd.Parameters.Add("Creator",Creator); 
OleCmd.Parameters.Add("ModifyBy",ModifyBy); 
OleCmd.Parameters.Add("Content",Content); 
OleCmd.Parameters.Add("ChannelID",ChannelID); 
OleCmd.Parameters.Add("IsOnTop",IsOnTop); 
OleCmd.Parameters.Add("IsCommend",IsCommend); 
OleCmd.Parameters.Add("IsCheck",IsCheck); 
OleCmd.Parameters.Add("Keyword",Keyword); 
//2004-2-2將文章增加簡介屬性 姜勇 
OleCmd.Parameters.Add("ArticleIntroduction",ArticleIntroduction); 
//執(zhí)行 
Erist.Common.Data.DataProvider.ExecNonQueryOle(OleCmd); 
return ArticleID; 
} 

注意看背景色為橙色的地方調(diào)用了Erist.Common.Data.DataProvider.GetAutoID()
下面是此方法的代碼

復(fù)制代碼代碼如下:

 
/**//// <summary> 
/// 取得數(shù)據(jù)集 
/// </summary> 
/// <param name="SqlCmd">執(zhí)行命令的SqlCommand</param> 
/// <returns>返回取得的數(shù)據(jù)集</returns> 
public static DataSet GetDataSetOle(OleDbCommand OleCmd ) 
{ 
OleDbDataAdapter t_DataAdapter ; 
DataSet t_DataSet=new DataSet(); 
try 
{ 
if (OleCmd.Connection.State != ConnectionState.Open) OleCmd.Connection.Open(); 
t_DataAdapter = new OleDbDataAdapter(OleCmd); 
t_DataAdapter.Fill(t_DataSet); 
return t_DataSet; 
} 
catch(Exception ex ) 
//捕獲數(shù)據(jù)層錯誤并返回給上一層。 
{ 
throw ex; 
} 
finally 
{ 
//斷開鏈接 
if (OleCmd.Connection.State == ConnectionState.Open) OleCmd.Connection.Close(); 

} 
} 

/**//// <summary> 
/// 取得某一表的最大字段值 
/// </summary> 
/// <param name="FieldName"></param> 
/// <param name="TableName"></param> 
/// <returns></returns> 
public static int GetAutoID(string FieldName ,string TableName,string ConnectString) 
{ 
DataSet ds; 
OleDbConnection OleCon=new OleDbConnection(ConnectString); 
OleDbCommand OleCmd=new OleDbCommand(); 
OleCmd.CommandText="Select Max(" + FieldName +") as MaxID from " + TableName; 
OleCmd.CommandType=System.Data.CommandType.Text; 
OleCmd.Connection=OleCon; 
ds=GetDataSetOle(OleCmd); 
if( ds.Tables[0].Rows[0][0] == DBNull.Value) 
{ 
return 1; 
} 
else 
{ 
return int.Parse(ds.Tables[0].Rows[0][0].ToString())+ 1; 
} 
}
