ElementValue Property (original) (raw)
Summary
Gets or sets the string value of the DICOM element being read.
Syntax
public string ElementValue { get; set; } public:
property String^ ElementValue
{
String^ get()
void set(String^ value)
}
Property Value
The string value of the DICOM element being read.
Remarks
If ElementDataType is ElementDataType.String, then this will be the value assigned to the DicomElement that will be created.
If ElementDataType is ElementDataType.Base64, then ElementValue contains a string that will be decoded accordingly, and then assigned to the DicomElement that will be created.
Modifying ElementValue changes the value that will be written for the DicomElement.
