// The '|' character is used to separate extended property name and its output format.
string value = extendedData["SUM_SQMI_A|F2"];

// Format string with number of the extended properties.
string value = extendedData["{CNTRY_NAME} Miles: {SUM_SQMI_A|F2}, KM: {SUM_SQKM_A|F1}"];
' Using of the single extended property name.
Dim value as String = extendedData("CNTRY_NAME")

' Using of the formatted extended property.
' The '|' character is used to separate extended property name and its output format.
Dim value as String = extendedData("SUM_SQMI_A|F2")

 Format string with number of the extended properties.
Dim value as String = extendedData("{CNTRY_NAME} Miles: {SUM_SQMI_A|F2}, KM: {SUM_SQKM_A|F1}")
