Creates a test control.

public void Text(string fmt);

Parameters

fmt System.String

The text to display.

Remarks

The fmt can take syntax for formatting values such as:

  • Numerical Formatting
    You can control how numeric values are displayed, including the number of decimal places,
    whether to use scientific notation, whether to include a thousand separator, and more.
    For example, {0:F2} formats the number with two decimal places.
  • Date and Time Formatting
    You can control how DateTime values are displayed, including the date format, time format, and more.
    For example, {0:yyyy-MM-dd} formats the date as year-month-day.
  • String Padding
    You can control the width of the field in which the string is printed, and whether it’s aligned to
    the left or right. For example, {0,10} prints the string in a field of width 10, right-aligned,
    while {0,-10} prints it left-aligned.
  • Custom Formatting
    You can define your own format strings to control how certain types of objects are displayed.
    can escape a brace by adding another brace.
    ple: {{ and }} will display as { and }.
