示例1: Main
// This example demonstrates the TextInfo.Clone() and
// TextInfo.ReadOnly() methods.
using System;
using System.Globalization;
class Sample
{
public static void Main()
{
// Get the TextInfo of a predefined culture that ships with
// the .NET Framework.
CultureInfo ci = new CultureInfo("en-US");
TextInfo ti1 = ci.TextInfo;
// Display whether the TextInfo is read-only or not.
DisplayReadOnly("1) The original TextInfo object", ti1);
Console.WriteLine();
// Create a clone of the original TextInfo and cast the clone to a TextInfo type.
Console.WriteLine("2a) Create a clone of the original TextInfo object...");
TextInfo ti2 = (TextInfo)ti1.Clone();
// Display whether the clone is read-only.
DisplayReadOnly("2b) The TextInfo clone", ti2);
// Set the ListSeparator property on the TextInfo clone.
Console.WriteLine("2c) The original value of the clone's ListSeparator " +
"property is \"{0}\".", ti2.ListSeparator);
ti2.ListSeparator = "/";
Console.WriteLine("2d) The new value of the clone's ListSeparator " +
"property is \"{0}\".\n", ti2.ListSeparator);
// Create a read-only clone of the original TextInfo.
Console.WriteLine("3a) Create a read-only clone of the original TextInfo object...");
TextInfo ti3 = TextInfo.ReadOnly(ti1);
// Display whether the read-only clone is actually read-only.
DisplayReadOnly("3b) The TextInfo clone", ti3);
// Try to set the ListSeparator property of a read-only TextInfo object. Use the
// IsReadOnly property again to determine whether to attempt the set operation. You
// could use a try-catch block instead and catch an InvalidOperationException when
// the set operation fails, but that programming technique is inefficient.
Console.WriteLine("3c) Try to set the read-only clone's LineSeparator " +
"property.");
if (ti3.IsReadOnly == true)
{
Console.WriteLine("3d) The set operation is invalid.");
}
else
{
// This clause is not executed.
ti3.ListSeparator = "/";
Console.WriteLine("3d) The new value of the clone's ListSeparator " +
"property is \"{0}\".\n", ti2.ListSeparator);
}
}
private static void DisplayReadOnly(string caption, TextInfo ti)
{
Console.WriteLine("{0} is {1}read-only.",
caption, ti.IsReadOnly ? "" : "not ");
}
}
输出:
1) The original TextInfo object is not read-only. 2a) Create a clone of the original TextInfo object... 2b) The TextInfo clone is not read-only. 2c) The original value of the clone's ListSeparator property is ",". 2d) The new value of the clone's ListSeparator property is "/". 3a) Create a read-only clone of the original TextInfo object... 3b) The TextInfo clone is read-only. 3c) Try to set the read-only clone's LineSeparator property. 3d) The set operation is invalid.
