LineNumber (RuntimeErrorEventArgs)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets the line number at which the run-time error occurred.
value = eventargs.LineNumber
Property Value
Type: integer
The number of the line on which the run-time error occurred.
This property is read/write but should be considered read-only because there is no reason to change the reported information. There is no default.
Managed Equivalent
No direct equivalent, but may be available within the message of an exception.
Remarks
This property is technically read/write, but there is generally no reason to set it, because the property is simply reporting information from existing errors.
Example
The following JavaScript example shows the portion of an event handler that displays error information specific to run-time errors.
// errorArgs is an instance of RuntimeErrorEventArgs.
if(errorArgs.ErrorType == "RuntimeError")
{
var runtimeErrorMsg = "Silverlight Runtime Error \n\n";
// Basic error event information.
runtimeErrorMsg += "Error Type: " + errorArgs.errorType + "\n";
runtimeErrorMsg += "Error Message: " + errorArgs.errorMessage + "\n";
runtimeErrorMsg += "Error Code: " + errorArgs.errorCode + "\n";
// Runtime-specific error event information.
if (errorArgs.lineNumber != 0)
{
runtimeErrorMsg += "Line: " + errorArgs.lineNumber + "\n";
runtimeErrorMsg += "Position: " + errorArgs.charPosition + "\n";
}
runtimeErrorMsg += "MethodName: " + errorArgs.methodName + "\n";
alert(runtimeErrorMsg);
}
