Well, it’s a bit hacky, but here we go.<\/p>\n

First thing to do is to get the HResult<\/code> from the exception. As it’s a protected member, we need a bit of reflection to get the value. Here’s an extension method to will do the trick:<\/p>\n

public static class ExceptionExtensions\n{\n    public static int HResultPublic(this Exception exception)\n    {\n        var hResult = exception.GetType().GetProperties(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance).Where(z => z.Name.Equals(\"HResult\")).First();\n        return (int)hResult.GetValue(exception, null);\n    }\n}\n<\/code><\/pre>\n
Now, in your catch scope, you can get the HResult<\/code>:<\/p>\n
catch (Exception ex)\n{\n    int hResult = ex.HResultPublic();\n}\n<\/code><\/pre>\n
From here, you’ll have to interpret the HResult. You’ll need this link.<\/p>\n
We need to get the ErrorCode<\/code> which is stored in the 16 first bits of the value, so here’s some bit operation:<\/p>\n
int errorCode = (int)(hResult & 0x0000FFFF);\n<\/code><\/pre>\n
Now, refer to the list of system error codes and here we are:<\/p>\n
ERROR_DISK_FULL\n112 (0x70)\n<\/code><\/pre>\n
So test it using:<\/p>\n
switch (errorCode)\n{\n    case 112:\n        \/\/ Disk full\n}\n<\/code><\/pre>\n
Maybe there are some “higher level” functions to get all this stuff, but at least it works.<\/p>\n","protected":false},"excerpt":{"rendered":"
