## Installation
To install `OData.QueryBuilder` from `Visual Studio`, find `OData.QueryBuilder` in the `NuGet` package manager user interface or enter the following command in the package manager console:
```
Install-Package OData.QueryBuilder
```

To add a link to the main dotnet project, run the following command line:
```
dotnet add package OData.QueryBuilder
```

## Usage

1. Build instance

As soon as possible, create a new instance of the OData.QueryBuilder object indicating the data models and the optional base path:

```csharp
    var odataQueryBuilder = new ODataQueryBuilder<Your OData root model>(<Your base url>?);
    
    // specify the resource for which the request will be built
    odataQueryBuilder.For<Your OData entity model>(s => s.ODataEntity)
    ```
    :information_source: __OData.Query Builder assumes you are using [OData Connected Service](https://marketplace.visualstudio.com/items?itemName=marketplace.ODataConnectedService) and you have a root model otherwise use:__
    
    ```csharp
    var odataQueryBuilder = new ODataQueryBuilder(<Your base url>?);
    
    // specify the resource for which the request will be built
    odataQueryBuilder.For<Your OData entity model>("ODataEntity")
    ```

2. Select request type

The builder allows you to build queries on the key and the list:
    * [ByKey](#ByKey)
      * [expand](#expand)
        * [filter](#filter)
        * [select](#select)
        * [orderby](#orderby)
        * [orderby desc](#orderbydesc)
        * [skip](#skip)
        * [top](#top)
        * [count](#count)
      * [select](#select) 
    * [ByList](#ByList)
      * [expand](#expand)
        * [filter](#filter)
        * [select](#select)
        * [orderby](#orderby)
        * [orderby desc](#orderbydesc)
        * [top](#top)
      * [filter](#filter)
      * [select](#select)
      * [orderby](#orderby)
      * [orderby desc](#orderbydesc)
      * [skip](#skip)
      * [top](#top)
      * [count](#count)
3. Get Uri request or collection of operators from the builder
    ```csharp
    odataQueryBuilder.ToUri()
    odataQueryBuilder.ToDictionary()
    ```

```
> $filter=ODataKind/ODataCode/Code in ('test%5C%5CYUYYUT','test1%5C%5CYUYY123')

## Using dynamic properties

For use-cases where a property which is used for queries needs to be dynamically resolved (eg. the user chooses the property name to filter on)
a special method `ODataProperty.FromPath<TProperty>()` can be invoked in the query expressions:

```csharp
...
.Filter(s => ODataProperty.FromPath<int>("IdRule") == 3))
```

Note that the generic type argument `TProperty` needs to match the type of the dynamically
resolved property in the OData model.

## Suppress exceptions

:warning: __May result in loss of control over the expected result.__

> Suppression of inclusion excludes the whole expression from the request

By default, suppression of function and operator argument exceptions is disabled. To enable it, you must pass the configuration `ODataQueryBuilderOptions` when initializing the builder
with initialization of the `SuppressExceptionOfNullOrEmptyFunctionArgs` and` SuppressExceptionOfNullOrEmptyOperatorArgs` properties.

```csharp
var builder = new ODataQueryBuilder<ODataInfoContainer>("http://mock/odata", new ODataQueryBuilderOptions {
    SuppressExceptionOfNullOrEmptyFunctionArgs = true,
    SuppressExceptionOfNullOrEmptyOperatorArgs = true,
});

var uri = builder
    .For<ODataTypeEntity>(s => s.ODataType)
    .ByList()
    .Filter((s, f, o) => o.In(s.ODataKind.ODataCode.Code, new string[0]) || o.In(s.ODataKind.ODataCode.Code, null)
        && f.Contains(s.ODataKind.ODataCode.Code, default(string)) 
        && o.In(s.IdType, new[] { 123, 512 }))
    .ToUri()
```
> http://mock/odata/ODataType?$filter=IdType in (123,512)

## ODataQueryBuilderOptions

### UseCorrectDateTimeFormat
> You should always manually set this option to `true` (__default__: `false`)
* `true` DateTime format `$"{dateTime:yyyy-MM-ddTHH:mm:sszzz}"` (with UTC offset)
* `false` DateTime format `$"{dateTime:s}Z"` (without UTC offset)
