@@ -14,7 +14,7 @@ Cannot modify members of 'variable' because it is a 'read-only variable type'
 
  This error occurs when you try to modify members of a variable which is read-only because it is in a special construct.  
 
- One common area that this occurs is within [foreach](../language-reference/statements/iteration-statements.md#the-foreach-statement) loops. It is a compile-time error to modify the value of the collection elements. Therefore, you cannot make any modifications to elements that are [value types](../language-reference/builtin-types/value-types.md), including [structs](../language-reference/builtin-types/struct.md). In a collection whose elements are [reference types](../language-reference/keywords/reference-types.md), you can modify accessible members of each element, but any try to add or remove or replace complete elements will generate [Compiler Error CS1656](../language-reference/compiler-messages/cs1656.md).
