Can I get specific metadata from a Func?

Question

Consider the following code:

string propertyName;
var dateList = new List() { DateTime.Now };
propertyName = dateList.GetPropertyName(dateTimeObj         


        

Answer 1

This is the version I use, it returns a PropertyInfo, but getting the name is trivial.

public static PropertyInfo GetProperty(Expression> expression)  
{
    MemberExpression memberExpression = null;

    if (expression.Body.NodeType == ExpressionType.Convert)
    {
        memberExpression = ((UnaryExpression) expression.Body).Operand as MemberExpression;
    }
    else if (expression.Body.NodeType == ExpressionType.MemberAccess)
    {
        memberExpression = expression.Body as MemberExpression;
    }

    if (memberExpression == null)
    {
        throw new ArgumentException("Not a member access", "expression");
    }

    return memberExpression.Member as PropertyInfo;
}
