  The returned resource is localized for the UI culture of the current thread, which is defined by the <xref:System.Globalization.CultureInfo.CurrentUICulture%2A?displayProperty=nameWithType> property. If the resource is not localized for that culture, the resource manager uses fallback rules to load an appropriate resource. If no usable set of localized resources is found, the <xref:System.Resources.ResourceManager> falls back on the default culture's resources. If a resource set for the default culture is not found, the method throws a <xref:System.Resources.MissingManifestResourceException> exception or, if the resource set is expected to reside in a satellite assembly, a <xref:System.Resources.MissingSatelliteAssemblyException> exception. If the resource manager can load an appropriate resource set but cannot find a resource named `name`, the method returns `null`.

 >  This method can throw more exceptions than are listed. One reason this might occur is if a method that this method calls throws an exception.  For example, a <xref:System.IO.FileLoadException> exception might be thrown if an error was made deploying or installing a satellite assembly, or a <xref:System.Runtime.Serialization.SerializationException> exception might be thrown if a user-defined type throws a user-defined exception when the type is deserialized.
