UInt64.MinValue Field
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Represents the smallest possible value of UInt64. This field is constant.
Assembly: mscorlib (in mscorlib.dll)
The following example uses the MinValue and MaxValue fields to verify that a Double value is within the range of the UInt64 type before it performs a type conversion. This prevents an OverflowException at run time.
double decimalValue = -1.5; ulong integerValue; // Discard fractional portion of Double value double decimalInteger = Math.Floor(decimalValue); if (decimalInteger < ulong.MaxValue && decimalInteger > ulong.MinValue) { integerValue = (ulong)decimalValue; outputBlock.Text += String.Format("Converted {0} to {1}.", decimalValue, integerValue) + "\n"; } else { ulong rangeLimit; string relationship; if (decimalInteger > ulong.MaxValue) { rangeLimit = ulong.MaxValue; relationship = "greater"; } else { rangeLimit = ulong.MinValue; relationship = "less"; } outputBlock.Text += String.Format("Conversion failure: {0} is {1} than {2}.", decimalInteger, relationship, rangeLimit) + "\n"; }
