var d1 = new Dictionary<string, int>();
var d2 = new Dictionary<string, int>();
var d3 = new Dictionary<string, int>();

var result = d1.Union(d2).Union(d3).ToDictionary (k => k.Key, v => v.Value);

编辑要确保没有重复的密钥，请使用：

var result = d1.Concat(d2).Concat(d3).GroupBy(d => d.Key)
             .ToDictionary (d => d.Key, d => d.First().Value);

只需循环它们：

var result = new Dictionary<string, string>();

foreach (var dict in dictionariesToCombine) {
    foreach (var item in dict) {
        result.Add(item.Key, item.Value);
    }
}

(假设dictionariesToCombine是您的字典中要组合的IEnumerable，例如数组。)
