C#字符串连接（开发人员如何使用）

public static void Main() 
{
    string firstName = "Iron";
    string lastName = "Developer";
    // Concatenate using String.Concat
    string fullName = String.Concat(firstName, " ", lastName);
    Console.WriteLine(fullName);
}

Public Shared Sub Main()
	Dim firstName As String = "Iron"
	Dim lastName As String = "Developer"
	' Concatenate using String.Concat
	Dim fullName As String = String.Concat(firstName, " ", lastName)
	Console.WriteLine(fullName)
End Sub

public static void Main() 
{
    string[] words = { "Hello", "World", "from", "C#" };
    // Use String.Join to join strings with a space as a delimiter
    string sentence = String.Join(" ", words);
    Console.WriteLine(sentence);
}

Public Shared Sub Main()
	Dim words() As String = { "Hello", "World", "from", "C#" }
	' Use String.Join to join strings with a space as a delimiter
	Dim sentence As String = String.Join(" ", words)
