使用的ToDictionary方法：

Use the ToDictionary method:

Dictionary<string, string> dString = dObject.ToDictionary(k => k.Key, k => k.Value.ToString());

在这里，您重用原来的字典中的键，就可以值转换为使用ToString方法字符串。

Here you reuse the key from the original dictionary and you convert the values to strings using the ToString method.

如果你的字典可以包含空值，你应该执行的ToString前添加一个空检查：

If your dictionary can contain null values you should add a null check before performing the ToString:

Dictionary<string, string> dString = dObject.ToDictionary(k => k.Key, k => k.Value == null ? "" : k.Value.ToString());

这部作品的原因是，词典<字符串对象> <字符串对象>> code>实际上是一个的IEnumerable&LT是。通过枚举上面的代码示例循环并建立使用ToDictionary方法一个新的字典。

The reason this works is that the Dictionary<string, object> is actually an IEnumerable<KeyValuePair<string,object>>. The above code example iterates through the enumerable and builds a new dictionary using the ToDictionary method.

编辑：

在NET 2.0，你不能使用ToDictionary方法，但你可以使用老式的foreach达到相同的：

In .Net 2.0 you cannot use the ToDictionary method, but you can achieve the same using a good old-fashioned foreach:

Dictionary<string, string> sd = new Dictionary<string, string>(); 
foreach (KeyValuePair<string, object> keyValuePair in dict)
{
  sd.Add(keyValuePair.Key, keyValuePair.Value.ToString());
}

EDIT2：

如果您是在NET 2.0，您可以在字典中的以下应该是安全有NULL值：

If you are on .Net 2.0 and you can have null values in the dictionary the following should be safe:

Dictionary<string, string> sd = new Dictionary<string, string>(); 
foreach (KeyValuePair<string, object> keyValuePair in dict)
{
  sd.Add(keyValuePair.Key, keyValuePair.Value == null ? "" : keyValuePair.Value.ToString());
}
