## CompareInfo::Compare(const String\&, const String\&, CompareOptions) const method


Compares strings. Only Ordinal and OrdinalIgnoreCase modes are supported.

```cpp
virtual int System::Globalization::CompareInfo::Compare(const String &a, const String &b, CompareOptions options) const
```


| Parameter | Type | Description |
| --- | --- | --- |
| a | const String\& | LHS string. |
| b | const String\& | RHS string. |
| options | CompareOptions | [String](../../../system/string/) comparison type. |

### ReturnValue

Negative value if LHS string preceeds RHS one, zero if they match, positive value otherwise.

| offset1 | int | Start index of characters in **string1**. |
| string2 | const String\& | Second string. |
| offset2 | int | Start index of characters in **string2**. |

### ReturnValue

Negative value if first string section preceeds second string section, zero if they match, positive value otherwise.
