Compiler Error CS1545

Property, indexer, or event 'property' is not supported by the language; try directly calling accessor methods 'set accessor' or 'get accessor'

The code is consuming an object that has a non-default indexer and tried to use the indexed syntax. To resolve this error, call the property's get or set accessor method.

Example 1

C++

// CPP1545.cpp  
// compile with: /clr /LD  
// a Visual C++ program  
using namespace System;  
public ref struct Employee {  
   Employee( String^ s, int d ) {}  
  
   property String^ name {  
      String^ get() {  
         return nullptr;  
      }  
   }  
};  
  
public ref struct Manager {  
   property Employee^ Report [String^] {  
      Employee^ get(String^ s) {  
         return nullptr;  
      }  
  
      void set(String^ s, Employee^ e) {}  
   }  
};  

Example 2

The following sample generates CS1545.

C#

// CS1545.cs  
// compile with: /r:CPP1545.dll  
  
class x {  
   public static void Main() {  
      Manager Ed = new Manager();  
      Employee Bob = new Employee("Bob Smith", 12);  
      Ed.Report[ Bob.name ] = Bob;   // CS1545  
      Ed.set_Report( Bob.name, Bob);   // OK  
   }  
}
