## XmlSchemaCollection::Add(const String\&, const String\&) method


Adds the schema located by the given URL into the schema collection.

```cpp
SharedPtr<XmlSchema> System::Xml::Schema::XmlSchemaCollection::Add(const String &ns, const String &uri)
```


| Parameter | Type | Description |
| --- | --- | --- |
| ns | const String\& | The namespace URI associated with the schema. For XML Schemas, this will typically be the **targetNamespace**. |
| uri | const String\& | The URL that specifies the schema to load. |

### ReturnValue

The [XmlSchema](../../xmlschema/) added to the schema collection; **nullptr** if the schema being added is an XDR schema or if there are compilation errors in the schema.

## XmlSchemaCollection::Add(const String\&, const SharedPtr\<XmlReader\>\&) method


Adds the schema contained in the [XmlReader](../../../system.xml/xmlreader/) to the schema collection.

```cpp
SharedPtr<XmlSchema> System::Xml::Schema::XmlSchemaCollection::Add(const String &ns, const SharedPtr<XmlReader> &reader)
```


| Parameter | Type | Description |
| --- | --- | --- |
| ns | const String\& | The namespace URI associated with the schema. For XML Schemas, this will typically be the **targetNamespace**. |
| reader | const SharedPtr\<XmlReader\>\& | [XmlReader](../../../system.xml/xmlreader/) containing the schema to add. |

### ReturnValue

The [XmlSchema](../../xmlschema/) added to the schema collection; **nullptr** if the schema being added is an XDR schema or if there are compilation errors in the schema.

## XmlSchemaCollection::Add(const String\&, const SharedPtr\<XmlReader\>\&, const SharedPtr\<System::Xml::XmlResolver\>\&) method


Adds the schema contained in the [XmlReader](../../../system.xml/xmlreader/) to the schema collection. The specified [XmlResolver](../../../system.xml/xmlresolver/) is used to resolve any external resources.

```cpp
SharedPtr<XmlSchema> System::Xml::Schema::XmlSchemaCollection::Add(const String &ns, const SharedPtr<XmlReader> &reader, const SharedPtr<System::Xml::XmlResolver> &resolver)
```


| Parameter | Type | Description |
| --- | --- | --- |
| ns | const String\& | The namespace URI associated with the schema. For XML Schemas, this will typically be the **targetNamespace**. |
| reader | const SharedPtr\<XmlReader\>\& | [XmlReader](../../../system.xml/xmlreader/) containing the schema to add. |
| resolver | const SharedPtr\<System::Xml::XmlResolver\>\& | The [XmlResolver](../../../system.xml/xmlresolver/) used to resolve namespaces referenced in **include** and **import** elements or **x-schema** attribute (XDR schemas). If this is **nullptr**, external references are not resolved. |

### ReturnValue

The [XmlSchema](../../xmlschema/) added to the schema collection; **nullptr** if the schema being added is an XDR schema or if there are compilation errors in the schema.

```


| Parameter | Type | Description |
