[Android.Runtime.Register("lastIndexOf", "(Ljava/lang/String;)I", "GetLastIndexOf_Ljava_lang_String_Handler")]
public virtual int LastIndexOf (string? str);
[<Android.Runtime.Register("lastIndexOf", "(Ljava/lang/String;)I", "GetLastIndexOf_Ljava_lang_String_Handler")>]
abstract member LastIndexOf : string -> int
override this.LastIndexOf : string -> int

Parameters

str
String

the substring to search for.

Returns

Int32

the index of the last occurrence of the specified substring, or -1 if there is no such occurrence.

Attributes
RegisterAttribute

Remarks

Returns the index within this string of the last occurrence of the specified substring. The last occurrence of the empty string "" is considered to occur at the index value this.length().

The returned index is the largest value k for which:

{@code
            this.toString().startsWith(str, k)
            }

If no such value of k exists, then -1 is returned.
