我正在尝试创建一个表示以下内容的表达式树:

myObject.childObjectCollection.Any(i => i.Name == "name");

为清楚起见,我有以下内容:

//'myObject.childObjectCollection' is represented here by 'propertyExp'
//'i => i.Name == "name"' is represented here by 'predicateExp'
//but I am struggling with the Any() method reference - if I make the parent method
//non-generic Expression.Call() fails but, as per below, if i use <T> the 
//MethodInfo object is always null - I can't get a reference to it

private static MethodCallExpression GetAnyExpression<T>(MemberExpression propertyExp, Expression predicateExp)
{
    MethodInfo method = typeof(Enumerable).GetMethod("Any", new[]{ typeof(Func<IEnumerable<T>, Boolean>)});
    return …
