否則,args[index].ToString() 會定義格式設定。 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,StringBuilder 實例的長度和容量都可以超出其 MaxCapacity 屬性的值。 當您呼叫 Append(String) 和AppendFormat...
[Android.Runtime.Register("append", "([CII)Ljava/lang/StringBuilder;", "")] public Java.Lang.IAppendable Append (char[]? str, int offset, int len); Parameters str Char[] the char[] to append. offset Int32 the inclusive offset index. len Int32 the number of characters. Returns ...
否则,args[index].ToString() 定义格式设置。 调用方说明 在.NET Core 和 .NET Framework 4.0 及更高版本中,通过调用 StringBuilder(Int32, Int32) 构造函数实例化 StringBuilder 对象时,StringBuilder 实例的长度和容量都可以超出其 MaxCapacity 属性的值。 尤其是在调用 Append(String) 和AppendFormat(String, ...
Append(Char[], Int32, Int32) Appends the string representation of a specified subarray of Unicode characters to this instance. C# Copy public System.Text.StringBuilder Append (char[]? value, int startIndex, int charCount); Parameters value Char[] A character array. startI...
public StringBuilder append(char[] str, int offset, int len) Appends the string representation of a subarray of the char array argument to this sequence. Characters of the char array str, starting at index offset, are appended, in order, to the contents of this sequence. The length of th...
