このインスタンスの値を増やすと MaxCapacity を超えます。 Enlarging the value of this instance would exceed MaxCapacity.

次の例で、AppendLineメソッド。The following example demonstrates the AppendLine method.

// This example demonstrates the StringBuilder.AppendLine()
// method.

using namespace System;
using namespace System::Text;

int main()
{
    StringBuilder^ sb = gcnew StringBuilder;
    String^ line = L"A line of text.";
    int number = 123;

    // Append two lines of text.
    sb->AppendLine( L"The first line of text." );
    sb->AppendLine( line );

    // Append a new line, an empty string, and a null cast as a string.
    sb->AppendLine();
    sb->AppendLine( L"" );
    sb->AppendLine( L"" );

    // Append the non-string value, 123, and two new lines.
    sb->Append( number )->AppendLine()->AppendLine();

    // Append two lines of text.
    sb->AppendLine( line );
    sb->AppendLine( L"The last line of text." );

    // Convert the value of the StringBuilder to a string and display the string.
    Console::WriteLine( sb );
