How to set the value of a property?

To set property values via Reflection, you must use the Type.GetProperty() method, then invoke the PropertyInfo.SetValue() method. The default overload that we used accepts the object in which to set the property value, the value itself, and an object array, which in our example is null.

How to set the value of a non indexed property?

The SetValue (Object, Object) overload sets the value of a non-indexed property. To determine whether a property is indexed, call the GetIndexParameters method. If the resulting array has 0 (zero) elements, the property is not indexed. To set the value of an indexed property, call the SetValue (Object, Object, Object []) overload.

Why is the set accessor not found in propertyinfo?

The property’s set accessor is not found. value cannot be converted to the type of PropertyType. The object does not match the target type, or a property is an instance property but obj is null. The number of parameters in index does not match the number of parameters the indexed property takes.

How to determine if a property is indexed in Java?

If this PropertyInfo object is a value type and value is null, then the property will be set to the default value for that type. To determine whether a property is indexed, use the GetIndexParameters method. If the resulting array has 0 (zero) elements, the property is not indexed. Access restrictions are ignored for fully trusted code.

To set property values via Reflection, you must use the Type.GetProperty () method, then invoke the PropertyInfo.SetValue () method. The default overload that we used accepts the object in which to set the property value, the value itself, and an object array, which in our example is null.

How to set the value of an indexed property?

If the resulting array has 0 (zero) elements, the property is not indexed. To set the value of an indexed property, call the SetValue (Object, Object, Object []) overload. If the property type of this PropertyInfo object is a value type and value is null, the property will be set to the default value for that type.

What happens if the property type of propertyinfo is null?

If the property type of this PropertyInfo object is a value type and value is null, the property will be set to the default value for that type.

What does the propertyinfo method do in Java?

The Type class’s GetProperties () method allows us to retrieve all properties within a type. This method returns an array of PropertyInfo objects. The PropertyInfo type provides us access to the metadata of a property. Sound confusing? Let’s just dive into some code and clear it up!
