Dynamic variables in objects

Lets say that I have a string that is mostly complete. In the middle of it is an entry that is variable - for example:

string speech = @"I am very"variable"and I need some lighter clothes"

Assuming I don't want to create another string to handle that last part of that sentence, how do I place one of many words for "hot" in place of variable?

My pseudo theory would go something like this:

string speech = @"I am very " + &antonym + " and I need some lighter clothes";
public string putTheSentenceTogether(string antonym)
{
    return speech(antonym);
}

Can this be done in C#? Or an any other way that doesn't require me to split speech up?

How about you do

string speech = @"I am very {0} and I need some lighter clothes";
public string PutTheSentenceTogether(string antonym)
{
    return string.Format(speech, antonym);
}

Or you can do (in C# 6.0 i.e. VS 2015 and later)

public string PutTheSentenceTogether(string antonym)
{
    return $"I am very {antonym} and I need some lighter clothes";
}

This will work using string interpolation:

public string putTheSentenceTogether(string antonym)
{
    return $"I am very {antonym} and I need some lighter clothes";
}

Or using string.Format

public string putTheSentenceTogether(string antonym)
{
    return string.Format("I am very {0} and I need some lighter clothes", antonym);
}

Provided you want to declare the string outside of the method, you could do

string speech = "I am very {0} and I need some lighter clothes";

public string putTheSentenceTogether(string antonym)
{
    return string.Format(speech, antonym);
}

Using C# 6.0 or later, try:

string myAntonym = "hot";
string speech = $"I am very {myAntonym} and I need some lighter clothes";
