泛型使用，及 动态显示多个类的属性名与值的 例子
1， 原代码：
#region ### ScriptTask List<PkgScriptTask> lstPkgScriptTask = pkgIndex.LstPkgScriptTask; if (lstPkgScriptTask != null && lstPkgScriptTask.Count > 0) { txtPkgInfo.AppendText("\r\n" + lstPkgScriptTask[0].GetType().ToString() + ":"); txtPkgInfo.AppendText("\r\nSTART analysizing---"); txtPkgInfo.AppendText("\r\n"); foreach (PkgScriptTask pbi in lstPkgScriptTask) // list title { foreach (System.Reflection.PropertyInfo info in typeof(PkgScriptTask).GetProperties()) { txtPkgInfo.AppendText(Convert.ToChar(Keys.Tab) + info.Name); } break; } txtPkgInfo.AppendText("\r\n"); foreach (PkgScriptTask pbi in lstPkgScriptTask) // list value { foreach (System.Reflection.PropertyInfo info in typeof(PkgScriptTask).GetProperties()) { txtPkgInfo.AppendText(Convert.ToChar(Keys.Tab) + info.GetValue(pbi, null).ToString()); } txtPkgInfo.AppendText("\r\n\r\n"); } txtPkgInfo.AppendText("END analysizing---\r\n"); } //OutputClassObj(lstPkgScriptTask,pkgIndex); #endregion ### ScriptTask2，通过泛型改进后的代码及调用示例
private void OutputClassObj<T>(List<T> t, PkgIndex pkgIndex) { List<T> lstPkgObj = new List<T>(); lstPkgObj = t; if (lstPkgObj != null && lstPkgObj.Count > 0) { txtPkgInfo.AppendText("\r\n" + lstPkgObj[0].GetType().ToString() + ":"); txtPkgInfo.AppendText("\r\nSTART analysizing---"); txtPkgInfo.AppendText("\r\n"); foreach (T pbi in lstPkgObj) // list title { foreach (System.Reflection.PropertyInfo info in typeof(T).GetProperties()) { txtPkgInfo.AppendText(Convert.ToChar(Keys.Tab) + info.Name); } break; } txtPkgInfo.AppendText("\r\n"); foreach (T pbi in lstPkgObj) // list value { foreach (System.Reflection.PropertyInfo info in typeof(T).GetProperties()) { txtPkgInfo.AppendText(Convert.ToChar(Keys.Tab) + info.GetValue(pbi, null).ToString()); } txtPkgInfo.AppendText("\r\n"); } txtPkgInfo.AppendText("END analysizing---\r\n"); } }调用示例：
private void OpenPkgIndex(PkgIndex pkgIndex) { #region ### basic Info List<PkgBasicInfo> lstPkgBasicInfo = pkgIndex.LstPkgBasicInfo; OutputClassObj(lstPkgBasicInfo, pkgIndex); #endregion ### basic info #region ### configuration List<PkgConfiguration> lstPkgConfiguration = pkgIndex.LstPkgConfig; OutputClassObj(lstPkgConfiguration, pkgIndex); #endregion ### configuration #region ### Connection List<PkgConnection> lstPkgConnection = pkgIndex.LstPkgConnection; OutputClassObj(lstPkgConnection, pkgIndex); #endregion ### Connection #region ### Variable List<PkgVariable> lstPkgVariable = pkgIndex.LstPkgVariable; OutputClassObj(lstPkgVariable, pkgIndex); #endregion ### Variable #region ### InputColumn List<PkgInputColumn> lstPkgInputColumn = pkgIndex.LstPkgInputColumn; OutputClassObj(lstPkgInputColumn, pkgIndex); #endregion ### InputColumn #region ### OutputColumn List<PkgOutputColumn> lstPkgOutputColumn = pkgIndex.LstPkgOutputColumn; OutputClassObj(lstPkgOutputColumn, pkgIndex); #endregion ### OutputColumn #region ### SqlScript List<PkgSqlScript> lstPkgSqlScript = pkgIndex.LstPkgSqlScript; OutputClassObj(lstPkgSqlScript, pkgIndex); #endregion ### ScriptTask #region ### ScriptTask List<PkgScriptTask> lstPkgScriptTask = pkgIndex.LstPkgScriptTask; OutputClassObj(lstPkgScriptTask, pkgIndex); #endregion ### ScriptTask }3，上述用到的几个类：（其实这几个类是在解析SSIS包时用到的）
