屬性值

型別:System. . :: . .String
A String that contains the connection manager or variable that contains the source folder or file information.

實作

IDTSFileSystemTask. . :: . .Source

備註

If the source is not a variable, then the source is a file connection manager. The IsSourcePathVariable property determines if it is a variable.

範例

The following code example creates a FileSystemTask as an Executable in a package. The FileSystemTask copies a test folder, which contains two subfolders and a .txt file, to another folder. The source is an existing folder, not a variable, so the IsSourcePathVariable is set to false, and the Source property is set to reference a FILE connection manager.
