PropertyInfo.CanRead Property

July 28, 2014

Gets a value indicating whether the property can be read.

Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

public abstract bool CanRead { get; }

Property Value

Type: System.Boolean
true if this property can be read; otherwise, false.

If the property does not have a get accessor, it cannot be read.

To get the CanRead property, first get the class Type. From the Type, get the PropertyInfo. From the PropertyInfo, get the CanRead value.

The following example defines two properties. The first property is readable, and the CanRead property is true. The second property is not readable (there is no get accessor), and the CanRead property is false.


using System;
using System.Reflection;

class Example
{
   // Define one readable property and one that is not readable.

   private string _caption = "A Default Caption";
   public string Caption   
   {
      get
      {
         return _caption;
      }
      set
      {
         if (_caption!=value)
         {
            _caption = value;
         }
      }
   }

   private string _text = "Default text";
   public string Text   
   {
      set
      {
         if (_text!=value)
         {
            _text = value;
         }
      }
   }

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      outputBlock.Text += "Reflection.PropertyInfo.CanRead\n\n";

      Example ex = new Example();

      outputBlock.Text += "Caption = " + ex.Caption + "\n";
      // The Text property cannot be read because it has no get accessor. The 
      // following line of code causes a compile error:
      //outputBlock.Text += "Text = " + ex.Text + "\n";

      PropertyInfo captionInfo = typeof(Example).GetProperty("Caption");
      PropertyInfo textInfo = typeof(Example).GetProperty("Text");

      // Display the CanRead properties.
      outputBlock.Text += 
         "CanRead for the Caption property: " + captionInfo.CanRead + "\n";
      outputBlock.Text += 
         "CanRead for the Text property: " + textInfo.CanRead + "\n";
   }
}

/* This example produces the following output:

Reflection.PropertyInfo.CanRead

Caption = A Default Caption
CanRead for the Caption property: True
CanRead for the Text property: False
 */
