Parameters

path1

A string containing the first path. [Edit]

path2

A string containing the second path. [Edit]

Returns

A string containing path1 followed by path2. If one of the specified paths is a zero length string, this method returns the other path. If path2 contains an absolute path, this method returns path2. [Edit]

Exceptions

Type	Reason
ArgumentNullException	path1 or path2 is null. [Edit]
ArgumentException	path1 or path2 contains one or more implementation-specific invalid characters. [Edit]

Remarks

If path1 does not end with a valid separator character (Path.DirectorySeparatorChar or Path.AltDirectorySeparatorChar), DirectorySeparatorChar is appended to path1 prior to the concatenation. [Edit]

Example

The following example demonstrates using the Combine method on a Windows system.

C# Example

using System; using System.IO; class CombineTest { public static void Main() { string path1, path2; Console.WriteLine("Dir char is {0} Alt dir char is {1}", Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar ); path1 = "foo.txt"; path2 = "\\ecmatest\\examples"; Console.WriteLine("{0} combined with {1} = {2}",path1, path2 , Path.Combine(path1, path2)); path1 = "\\ecmatest\\examples"; path2 = "foo.txt"; Console.WriteLine("{0} combined with {1} = {2}",path1, path2 , Path.Combine(path1, path2)); } }

The output is

Dir char is \ Alt dir char is /
foo.txt combined with \ecmatest\examples = \ecmatest\examples
\ecmatest\examples combined with foo.txt = \ecmatest\examples\foo.txt
