Using PropertyInfo to determine the type of property

Question

I want to dynamically parse a tree of objects in order to perform some random check. Validation is not important as such, but I want to better understand the PropertyInfo class.

I will do something like this,

public bool ValidateData(object data) { foreach (PropertyInfo propertyInfo in data.GetType().GetProperties()) { if (the property is a string) { string value = propertyInfo.GetValue(data, null); if value is not OK { return false; } } } return true; } 

In fact, the only part I care about right now is "if the property is a string." How can I find out from the PropertyInfo object what type it is.

I will have to deal with basic things like strings, ints, double. But I will also have to deal with objects, and if so, I will need to traverse the tree of objects further inside these objects in order to check the main data inside them, they will also have rows, etc.

Thank.

Use PropertyInfo.PropertyType to get the property type.

 public bool ValidateData(object data) { foreach (PropertyInfo propertyInfo in data.GetType().GetProperties()) { if (propertyInfo.PropertyType == typeof(string)) { string value = propertyInfo.GetValue(data, null); if value is not OK { return false; } } } return true; }
