## String::IndexOfAny(char_t, int) const method


Character forward lookup.

```cpp
int System::String::IndexOfAny(char_t c, int startIndex=0) const
```


| Parameter | Type | Description |
| --- | --- | --- |
| c | char_t | Character to look for. |
| startIndex | int | [Index](../../index/) to start lookup at. |

### ReturnValue

[Index](../../index/) of first character position since startIndex or -1 if not found.

## String::IndexOfAny(const ArrayPtr\<char_t\>\&) const method


Looks for any of passed characters through the whole string. Compares first string character to all characters in anyOf, then compares second one and so on. Returns index of the first one matching any of the target characters.

```cpp
int System::String::IndexOfAny(const ArrayPtr<char_t> &anyOf) const
```


| Parameter | Type | Description |
| --- | --- | --- |
| anyOf | const ArrayPtr\<char_t\>\& | [Array](../../array/) of characters to look for. Order doesn't matter. |

### ReturnValue

[Index](../../index/) of the first matching character or -1 if not found.

## String::IndexOfAny(const ArrayPtr\<char_t\>\&, int32_t) const method


Looks for any of passed characters through substring. Compares first string character to all characters in anyOf, then compares second one and so on. Returns index of the first one matching any of the target characters.

```cpp
int System::String::IndexOfAny(const ArrayPtr<char_t> &anyOf, int32_t startindex) const
```


| Parameter | Type | Description |
| --- | --- | --- |
| anyOf | const ArrayPtr\<char_t\>\& | [Array](../../array/) of characters to look for. Order doesn't matter. |
| startindex | int32_t | [Index](../../index/) to start lookup from. |

### ReturnValue

[Index](../../index/) of the first matching character or -1 if not found.

## String::IndexOfAny(const ArrayPtr\<char_t\>\&, int32_t, int32_t) const method


Looks for any of passed characters through substring. Compares first string character to all characters in anyOf, then compares second one and so on. Returns index of the first one matching any of the target characters.

```cpp
int System::String::IndexOfAny(const ArrayPtr<char_t> &anyOf, int32_t startindex, int32_t count) const
```


| Parameter | Type | Description |
| --- | --- | --- |
| anyOf | const ArrayPtr\<char_t\>\& | [Array](../../array/) of characters to look for. Order doesn't matter. |
| startindex | int32_t | [Index](../../index/) to start lookup from. |
| count | int32_t | Number of characters to look through. |

### ReturnValue

[Index](../../index/) of the first matching character or -1 if not found.

## String::IndexOfAny(const String\&, int) const method


Consequently looks for all characters of str in this. If first character is found, its position is returned, otherwise looks for the second one and so on.

```cpp
int System::String::IndexOfAny(const String &str, int startIndex=0) const
```


| Parameter | Type | Description |
| --- | --- | --- |
| str | const String\& | [String](../) of characters to look for. Order of characters matters. |
| startIndex | int | Position to start lookup from. |

### ReturnValue

[Index](../../index/) of first found character or -1 if none is found.
