TargetParameterCountException when enumerating through properties of string

Question

I\'m using the following code to output values of properties:

string output = String.Empty;
string stringy = \"stringy\";
int inty = 4;
Foo spong = new Foo() {Na         


        

Answer 1

In this case, one of the string's properties is the indexer for returning the character at the specified location. Thus, when you try to GetValue, the method expects an index but doesn't receive one, causing the exception.

To check which properties require index you can call GetIndexParameters on the PropertyInfo object. It returns an array of ParameterInfo, but you can just check the length of that array (if there are no parameters, it will be zero)
