ToCompilerGeneratedBackingField(String)

Converts the property name to the one of the compiler-generated backing field. This can be used for the field-based reflection when you want to set the value of a get-only property

public static string ToCompilerGeneratedBackingField(string propertyName)
Parameters
Type Name Description
System.String propertyName

Name of the property
Returns
Type Description
System.String

Name of the backing field
Remarks

Only works for properties with compiler-generated backing fields. This is only a simple method and doesn't have any guarantees to work 100% of the time across different compilers/runtimes. See this link for more info.
