範例

下列範例示範 AppendLine 方法。

// 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 );

    return 0;

備註

預設行結束字元是 屬性的 Environment.NewLine 目前值。

視需要調整此實例的容量。

給呼叫者的注意事項

在 .NET Core 和 .NET Framework 4.0 和更新版本中,當您藉由呼叫 StringBuilder(Int32, Int32) 建構函式來具現化 StringBuilder 物件時,實例的 StringBuilder 長度和容量都可以成長超過其 MaxCapacity 屬性的值。 當您呼叫 Append(String)AppendFormat(String, Object) 方法來附加小型字串時,就會發生此情況。
