StringBuilder.Append Method (Int64)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Appends the string representation of a specified 64-bit signed integer to the end of this instance.
Assembly: mscorlib (in mscorlib.dll)
Enlarging the value of this instance would exceed its maximum capacity.
The method modifies the existing instance of this class; it does not return a new class instance. Because of this, you can call a method or property on the existing reference and you do not have to assign the return value to a StringBuilder object, as the following example illustrates.
System.Text.StringBuilder sb = new System.Text.StringBuilder("The range of a 64-bit integer: "); sb.Append(Int64.MinValue).Append(" to ").Append(Int64.MaxValue); outputBlock.Text += sb + Environment.NewLine; // The example displays the following output: // The range of a 64-bit integer: -9223372036854775808 to 9223372036854775807
The capacity of this instance is adjusted as needed.
