M:Windows.Foundation.Collections.IVector`1.IndexOf(`0,System.UInt32@) |
winrt method |
Retrieves the index of a specified item in the vector.
The item to find in the vector.
If the item is found, this is the zero-based index of the item; otherwise, this parameter is 0.
true if the item is found; otherwise, false.
When programming with .NET, this interface is hidden, and you should use the System.Collections.Generic.IList<T> interface.
If the index parameter is 0, it indicates that the item is the first item in the array or that the item was not found. To determine whether the item found is the first item, check the return value of this method before you check the index parameter. If the return value is true and index is 0, then the item is the first item in the array. If the return value is false, then the item was not found and index is 0.
