public static string SubstituteVariables(
	string value,
	IDictionary props
)

Public Shared Function SubstituteVariables ( 
	value As String,
	props As IDictionary
) As String

public:
static String^ SubstituteVariables(
	String^ value, 
	IDictionary^ props
)

static member SubstituteVariables : 
        value : string * 
        props : IDictionary -> string 

Parameters

value

Type: SystemString
The string on which variable substitution is performed.

props

Type: System.CollectionsIDictionary
The dictionary to use to lookup variables.

Return Value

The variable substitution delimiters are ${ and }.

For example, if props contains key=value, then the call

string s = OptionConverter.SubstituteVariables("Value of key is ${key}.");

will set the variable s to "Value of key is value.".

If no value could be found for the specified key, then substitution defaults to an empty string.

For example, if system properties contains no value for the key "nonExistentKey", then the call

string s = OptionConverter.SubstituteVariables("Value of nonExistentKey is [${nonExistentKey}]");

will set s to "Value of nonExistentKey is []".

An Exception is thrown if value contains a start delimiter "${" which is not balanced by a stop delimiter "}".
