IPropertyDatabaseView.TryLoad

参数

返回

bool True if the record is found and is valid, false otherwise.

描述

Loads a single property, already deseriazed into an object.

// Load the value already deserialized.
using (var view = propertyDatabase.GetView())
{
    var colorRecordKey = view.CreateRecordKey("path/to/my/asset", "m_Color");
    if (!view.TryLoad(colorRecordKey, out object colorObject))
        Assert.Fail("Failed to load color property.");
    var color = (Color)colorObject;
    Assert.AreEqual(new Color(1, 0, 1), color);
}

参数

返回

bool True if the record is found and is valid, false otherwise.

描述

Loads a single property, still contained within a record.

This method doesn't deserialize the value. You have to deserialize it yourself by calling IPropertyDatabaseView.GetObjectFromRecordValue.

// Load the record value to do a deserialization at the appropriate time.
using (var view = propertyDatabase.GetView())
{
    var sizeRecordKey = view.CreateRecordKey("path/to/my/asset", "m_Size");
    if (!view.TryLoad(sizeRecordKey, out IPropertyDatabaseRecordValue sizeRecordValue))
        Assert.Fail("Failed to load size property.");
    var size = view.GetValueFromRecord<int>(sizeRecordValue);
    Assert.AreEqual(42, size);
}

参数

返回

bool True if the record is found and is valid, false otherwise.

描述

Loads all the properties of a document, already deseriazed into objects.

// Load all values not associated with a document, already deserialized.
using (var view = propertyDatabase.GetView())
{
    var nullDocumentKey = view.CreateDocumentKey(null);
    if (!view.TryLoad(nullDocumentKey, out IEnumerable<object> noDocumentProperties))
        Assert.Fail("Failed to load properties with no documents.");
    Assert.IsNotEmpty(noDocumentProperties);
    Assert.AreEqual("myDocs_", noDocumentProperties.First());
}
