How to insert one string into another using Insert() in C#
Theodore Kelechukwu OnyejiakuOverview
In C#, the Insert() method takes a string and inserts it into another string. Insert() accepts the index position to start the insertion from, inserts the second string at the index position of the first string, and then returns the modified string.
Syntax
public string Insert(int32 first, String second)
Parameters
first: The index position to start the insertion at.second: The string we want to insert into another.
Return value
The Insert method returns a modified string.
Code example
The example below demonstrates the use of the Insert method to insert a string into another string.
// create our class
class StringInserter
{
// main method
static void Main()
{
// create strings to insert to
string str1 = "Hlo";
string str2 = "ld";
// insert strings to the string above
string modStr1 = str1.Insert(1, "el");
string modStr2 = str2.Insert(0, "wor");
// print returned modified strings
System.Console.WriteLine(modStr1);
System.Console.WriteLine(modStr2);
}
}In the code above, we insert "el" to "Hlo", starting from the second position, to form "Hello". We also insert "wor" to "ld", thus modifying it to "world". This is the use of the Insert() method in C#.
