Example code Analysis for ASP. NET using reflection to assign values to the model class

This article mainly introduces the method of using the reflection to realize the assignment of the model class, and analyzes the operation steps and the related operation skill of ASP to use the reflection to the model class.

The example in this article describes how ASP. NET uses reflection to implement the method of assigning a value to the model class. Share to everyone for your reference, as follows:

<summary>///automatically assigns a value to the Model class//</summary>///<param name= "SqlString" > Gets the SQL statement that queries a model instance </ param>///<param name= "obj" >model instance object </param>///<returns></returns>public Object Selmodel (string Sqlstring,object obj) {DataTable Dtsell = lcommonbll.  GetTable (SqlString); int count = Dtsell.  Rows.Count;  if (count = = 0) {return null; } else {DataRow Dr = Dtsell.   Rows[0]; #region Another method//foreach (DataColumn col in Dr. Table.columns)//{//PropertyInfo pt = seller. GetType (). GetProperty (Col.   ColumnName); if (String.IsNullOrEmpty (Dr[col. ColumnName].   ToString ()))//{//break; }//else//{//PT. SetValue (seller, Dtsell.   ROWS[0][0], NULL); }//} #endregion foreach (System.Reflection.PropertyInfo pi in obj. GetType (). GetProperties ()) {if (pi). CanWrite) {try {if (Dtsell). Rows[0][pi. Name]!=null) {pi. SetValue (obj, Dtsell. Rows[0][pi.      Name], NULL);       } else {Pi.      SetValue (obj, null, NULL); }} catch {pi.     SetValue (obj, null, NULL);  }}} return obj; }}
