'casting' with reflection

Question

Consider the following sample code:

class SampleClass
{
    public long SomeProperty { get; set; }
}

public void SetValue(SampleClass instance, decimal valu         


        

Answer 1

When the Type is a Nullable Guid then none of the above proposed solutions work. Invalid cast from 'System.DBNull' to 'System.Guid' exception is thrown at Convert.ChangeType

To fix that change to:

var convertedValue = value == System.DBNull.Value ? null : Convert.ChangeType(value, targetType);
