[ 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 single-precision floating-point number to the end of this instance.
Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public Function Append ( _
value As Single _
) As StringBuilder
public StringBuilder Append(
float value
)
Parameters
- value
Type: System..::.Single
The value to append.
Return Value
Type: System.Text..::.StringBuilder
A reference to this instance after the append operation has completed.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | Enlarging the value of this instance would exceed its maximum capacity. |
Remarks
The Append 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.
Dim value As Single = 1034769.47
Dim sb As New System.Text.StringBuilder()
sb.Append("*"c, 5).Append(value).Append("*"c, 5)
outputBlock.Text += sb.ToString() + Environment.NewLine
' The example displays the following output:
' *****1034769.47*****
float value = 1034769.47f;
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append('*', 5).Append(value).Append('*', 5);
outputBlock.Text += sb + Environment.NewLine;
// The example displays the following output:
// *****1034769.47*****
The Append method calls the Single..::.ToString method to get the string representation of value for the current culture. To control the formatting of value, call the AppendFormat method.
The capacity of this instance is adjusted as needed.
