string[] keys = dictionary.Keys.ToArray(); Otherwise, you will have to use the CopyTo method, or use a loop : string[] keys = new string[dictionary.Keys.Count]; dictionary.Keys.CopyTo(keys, 0);
These days, once you have LINQ available, you can convert the dictionary keys and their values to a single string. You can use the following code: // convert the dictionary to an array of strings. string[] strArray = dict.Select(x => ("Key: " + x.Key + ", Value: " + x.Value)).ToArray();
string.Join ( ",", someDictionary.Select(pair => string.Format("{0}={1}", pair.Key.ToString(), pair.Value.ToString())).ToArray() ); First you iterate each key-value pair and format it as you'd like to see as string, and later convert to array and join into a single string.
7 kwi 2022 · This post will discuss how to convert Dictionary values to an Array in C#... The idea is to allocate an array to accommodate all the values of the dictionary, and then use the CopyTo() method to copy values from the dictionary to the array.
Converts the value of objects to strings based on the formats specified and inserts them into another string. If you are new to the String.Format method, see Get started with the String.Format method for a quick overview.
Copies the string dictionary values to a one-dimensional Array instance at the specified index. public: virtual void CopyTo(Array ^ array, int index); public virtual void CopyTo (Array array, int index);
If you have a dictionary in C# and you want to convert its values into an array, you can use the Values property of the Dictionary<TKey, TValue> class and then use the ToArray method. Here's an example:
