Erist.Common.Data.DataProvider.ExecNonQueryOle(OleCmd); 
return ArticleID; 
} 
 
注意看背景色为橙色的地方调用了Erist.Common.Data.DataProvider.GetAutoID() 
下面是此方法的代码 
 代码如下:

/**//// <summary> 
/// 取得数据集 
/// </summary> 
/// <param name="SqlCmd">执行命令的SqlCommand</param> 
/// <returns>返回取得的数据集</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 ) 
//捕获数据层错误并返回给上一层。 
{ 
throw ex; 
} 
finally 
{ 
//断开链接 
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; 
} 
} 
 
根据传过来的FieldName 和TableName 来读数据库当前最大的FieldName 如果没有返回1 
有则在此基础上+1 因为是要获取要添加记录的唯一FieldName 
此处FieldName是ArticleID 
此方法还是不错的.
