| Exception | Condition |
|---|---|
| ArgumentException | fromPath is not rooted. - or - toPath is not rooted. |
If the fromPath and toPath parameters are not rooted; that is, they do not equal the root operator (the tilde [~]), do not start with a tilde (~), such as a tilde and a slash mark (~/) or a tilde and a double backslash (~//), or do not start with a slash mark (/), an ArgumentException exception is thrown.
Query string parameters and HTML anchors that are used in the URI are not used in determining the relative path.
If fromPath is "/directory1/file1.aspx" and toPath is "/directory2/file2.aspx", the MakeRelative method returns "../directory2/file2.aspx".
