Method TryGetValue
TryGetValue<T>(string, out T?)

Declaration
public bool TryGetValue<T>(string key, out T? value) where T : IParsable<T>Parameters
| Type | Name | Description |

TryGetValue<T>(string, bool, out T?)
Attempts to get the value associated with the specified key, parsed as the specified type using invariant culture formatting, with control over whether parsing errors should be treated as missing keys.
Declaration
public bool TryGetValue<T>(string key, bool throwOnParseError, out T? value) where T : IParsable<T>Parameters
| Type | Name | Description |
|---|---|---|
| string | key | The query parameter key. |
| bool | throwOnParseError | If true, a FormatException is thrown when parsing fails; otherwise, parsing errors are treated as missing keys. |
