PropertyInfo.CanRead Property

public:
 abstract property bool CanRead { bool get(); };

public abstract bool CanRead { get; }

member this.CanRead : bool

Public MustOverride ReadOnly Property CanRead As Boolean

Property Value

true if this property can be read; otherwise, false.

Examples

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;

// Define one readable property and one not readable.
public class Mypropertya
{
    private string caption = "A Default caption";
    public string Caption
    {
        get{return caption;}
        set {if(caption!=value) {caption = value;}
        }
    }
}
public class Mypropertyb
{
    private string caption = "B Default caption";
    public string Caption
    {
        set{if(caption!=value) {caption = value;}
        }
    }
}

class Mypropertyinfo
{
    public static int Main()
    {
        Console.WriteLine("\nReflection.PropertyInfo");

        // Define two properties.
        Mypropertya Mypropertya = new Mypropertya();
        Mypropertyb Mypropertyb = new Mypropertyb();

        Console.Write("\nMypropertya.Caption = " + Mypropertya.Caption);
        // Mypropertyb.Caption cannot be read, because
        // there is no get accessor.

        // Get the type and PropertyInfo.
        Type MyTypea = Type.GetType("Mypropertya");
        PropertyInfo Mypropertyinfoa = MyTypea.GetProperty("Caption");
        Type MyTypeb = Type.GetType("Mypropertyb");
        PropertyInfo Mypropertyinfob = MyTypeb.GetProperty("Caption");

        // Get and display the CanRead property.
        Console.Write("\nCanRead a - " + Mypropertyinfoa.CanRead);
        Console.Write("\nCanRead b - " + Mypropertyinfob.CanRead);

        return 0;
    }
}

           Mypropertyinfob.CanRead)

        Return 0
    End Function
End Class

Remarks

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.
