Tips for Traversing attributes and values of an object Using Reflection in C #

This article describes how to use reflection to traverse the attributes and values of an object in C #. This is useful in most cases. This article provides the instance Code directly. For more information, see

Summary:

Corresponding to the instantiated object tc of a class, traverse the method for getting all attributes (sub-members) (Using Reflection ):

The Code is as follows:

Type t = tc. GetType (); // obtain the Type of this class

// Use Type. GetProperties to obtain PropertyInfo [], and then you can use foreach to traverse it.

Foreach (PropertyInfo pi in t. GetProperties ())

{

Object value1 = pi. GetValue (tc, null); // use pi. GetValue to obtain the value

String name = pi. Name; // obtain the attribute name. You can determine the Name to perform the operations you want.

// Obtain the attribute type, perform judgment, and perform subsequent operations. For example, the obtained attribute is an integer.

If (value1.GetType () = typeof (int ))

{

// Perform the operation you want

}

}

Note:

The get and set attributes must be set before reflection can obtain the attributes.

The Code is as follows:

Public int Pid

{

Get {return pid ;}

Set {pid = value ;}

}
