Appends the command line with file name represented by the parameter, inserting quotation marks if necessary.
Overloads
| AppendFileNameIfNotNull(ITaskItem) |
Appends a file name quoting it if necessary. This method appends a space to the command line (if it's not currently empty) before the file name. |
| AppendFileNameIfNotNull(String) |
Appends a file name quoting it if necessary. This method appends a space to the command line (if it's not currently empty) before the file name. |
Examples
The following example creates a ToolTask that runs Ilasm.exe (IL Assembler). The CommandLineBuilder, ToolLocationHelper, and TaskLoggingHelper classes are used to generate the information needed to run the task.

Remarks
This method appends the command line with a task item specification, and surrounds task item specification with quotations marks as necessary.
If the command line is not empty, then this method also appends the command line with a space, before the task item specification.
Applies to
AppendFileNameIfNotNull(String)
- Source:
- CommandLineBuilder.cs
Appends a file name quoting it if necessary. This method appends a space to the command line (if it's not currently empty) before the file name.
public:
void AppendFileNameIfNotNull(System::String ^ fileName);public void AppendFileNameIfNotNull (string fileName);member this.AppendFileNameIfNotNull : string -> unitPublic Sub AppendFileNameIfNotNull (fileName As String)Parameters
- fileName
- String
File name to append, if it's null this method has no effect
Examples
AppendFileNameIfNotNull("-StrangeFileName.cs") yields .\-StrangeFileName.cs.
AppendFileNameIfNotNull("-StrangeFileName.cs") => ".-StrangeFileName.cs"
Remarks
This method appends the command line with a file name, and surrounds the file name with quotation marks as necessary.
If the first character of the file name is a dash, then .\ is added to the beginning of the file name to distinguish it from a switch.
If the command line is not empty, then this method also appends the command line with a space, before the file name.
