1、OracleClient //基於.NET 2.0，只有2.0中包含OracleClient using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Web; using System.Web.Services; using System.Web.Services.Protocols; using System.Security.Cryptography; using System.IO; using System.Collections.Generic; using System.Configuration; using System.Data.SqlClient; using System.Data.OracleClient; public partial class orclService : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.AddHeader("Access-Control-Allow-Origin", "*"); List<info> result = new List<info>(); string callback = Request.QueryString["method"]; if (callback == "getTableInfo") result = getTableInfo(); Response.Write(result); Response.End(); } //<add key="orclCon" value="Data Source=ORCL;User Id=sa;Password=123;"/> private static string strConn = ConfigurationSettings.AppSettings["orclCon"]; [WebMethod(Description = "<h3>Oracle連線測試</h3>")] public List<info> getTableInfo() { List<info> list = new List<info>(); OracleConnection conn = new OracleConnection(strConn); conn.Open(); string strComm = "select * from ATEST_POLYGON"; OracleCommand comm = new OracleCommand(strComm, conn); OracleDataReader sdr = comm.ExecuteReader(); info strInfo = null; while (sdr.Read()) { strInfo = new info(); strInfo.ID = sdr["ID"].ToString(); strInfo.Content = sdr["CONTENT"].ToString(); list.Add(strInfo); } if (!sdr.HasRows) { strInfo.Content = "無匹配記錄"; list.Add(strInfo); } sdr.Close(); return list; } public class info { private string id; public string ID { get { return this.id; } set { this.id = value; } } private string content; public string Content { get { return this.content; } set { this.content = value; } } } } 2、ODBC（參見“Oracle 通過 ODBC 連線”） using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Linq; using System.Web; using System.Web.Services; using System.Web.Services.Protocols; using System.Xml.Linq; using System.Security.Cryptography; using System.IO; using System.Collections.Generic; using System.Configuration; using System.Data.SqlClient; using System.Data.Odbc; public partial class orclService : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.AddHeader("Access-Control-Allow-Origin", "*"); int result = 0; string callback = Request.QueryString["method"]; if (callback == "getTableInfo") result = getTableInfo(); Response.Write(result); Response.End(); } //<add key="orclCon_windows" value="DSN=oracle_windows;UID=sa;PWD=123;"/> // <add key="orclCon_linux" value="DSN=oracle_linux;UID=sde;PWD=sde;"/> private static string strConn = ConfigurationSettings.AppSettings["orclCon_linux"]; [WebMethod(Description = "<h3>Oracle連線測試</h3>")] public int getTableInfo() { OdbcConnection odbcconn = new OdbcConnection(strConn); odbcconn.Open(); string strComm = "select * from ATEST_POLYGON"; OdbcDataAdapter odbcda = new OdbcDataAdapter(strComm, odbcconn); DataSet ds = new DataSet(); odbcda.Fill(ds); DataTable dt = new DataTable(); dt = ds.Tables[0]; odbcconn.Close(); odbcconn.Dispose(); return dt.Rows.Count; } } 3、OLEDB using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Linq; using System.Web; using System.Web.Services; using System.Web.Services.Protocols; using System.Xml.Linq; using System.Security.Cryptography; using System.IO; using System.Collections.Generic; using System.Configuration; using System.Data.SqlClient; using System.Data.OleDb; public partial class orclService : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.AddHeader("Access-Control-Allow-Origin", "*");

[WebMethod(Description = "<h3>Oracle連線測試</h3>")] public List<info> getTableInfo() { List<info> list = new List<info>(); OleDbConnection conn = new OleDbConnection(strConn); conn.Open(); string strComm = "select * from ATEST_POLYGON"; OleDbCommand comm = new OleDbCommand(strComm, conn); OleDbDataReader sdr = comm.ExecuteReader(); info strInfo = null; while (sdr.Read()) { strInfo = new info(); strInfo.ID = sdr["ID"].ToString(); strInfo.Content = sdr["CONTENT"].ToString(); list.Add(strInfo); } if (!sdr.HasRows) { strInfo.Content = "無匹配記錄"; list.Add(strInfo); } sdr.Close(); return list; conn.Close(); conn.Dispose(); return list; } public class info { private string id; public string ID { get { return this.id; } set { this.id = value; } } private string content; public string Content { get { return this.content; } set { this.content = value; } } } }
