Parameters

fileName

Type: SystemString
The name of the assembly associated with an AFPlugIn to be resolved.

fileVersion (Optional)

Type: SystemString
The file version of the assembly associated with an AFPlugIn to be resolved. If , then this method will resolve to the latest version of the assembly.

loadProperties (Optional)

Type: OSIsoft.AFAFPlugInLoadProperties
Any AFPlugInLoadProperties associated with loading the specified assembly. If not specified, then the Default load properties are used.

defaultOnly (Optional)

Type: SystemBoolean
If , the only the default plugin assembly directory will be searched for the plugin and the fileVersion parameter will be ignored. The default value for this property is .

Return Value

This helper method resolves an assembly associated with an AFPlugIn to a full path name. This can then be used with the LoadFrom(String) method to load the assembly.

Plugins loaded from the server are stored in the OSIsoft\AF\PlugIns directory under the CommonApplicationData directory. Each plugin is stored in a sub-directory based upon its version. The resolved path returned searches for the plugin under the directory that matches the fileVersion parameter if specified. A default plugin can be stored in the root OSIsoft\AF\PlugIns directory. This method returns the highest version of the plugin that is compatible with loadProperties.
